How to Inflate a Basketball (What You Need + 5 Steps)
Inflating a basketball is not something you really need to do all that often. When you buy a brand new basketball, it is usually already inflated so you really don’t think too much about it. After a while, basketballs tend to lose a little air and if you let one sit around for a long time, it will definitely end up flat.
Even an often used basketball will eventually need air. You may go out to play a game and notice that your ball is not bouncing quite as it should. Cold weather may also lower the pressure in a basketball making it seem unresponsive when you dribble and shoot. In either case, you can always add a little air to solve the problem.
Why should you care if your basketball is properly inflated? How do you know when your basketball is properly inflated? What is the best way to properly inflate your basketball? These are all common questions with fairly simple answers. Let’s take a look at each question one at a time.
Why Should I Properly Inflate My Basketball?
A properly inflated basketball will ensure that your practice, one-on-one game, full-court five-on-five game or even your game of HORSE is the best experience that it can be. An underinflated ball will not have any “action”, meaning it will not bounce very well, which will make it more difficult to dribble. Also, it will not bank off the backboard as well and bounce passes will not go as far as you intend them to go.
An overinflated ball can be bad as well. It will bounce too high when you dribble, bank too hard off the backboard and bounce passes will go farther than you intend them to go. This is why it is important to have your basketball inflated to the specified pressure or at least near the specified pressure.
How Do I know If My Basketball is Properly Inflated?
The standard pressure recommended for a basketball is 7 – 9 PSI (48.26 – 62.05 kPa). Unless you have a pressure gauge, and many air pumps do (we’ll talk about that in the next section), then you will not know what the air pressure in your basketball is. Not to worry, there is a simple method that you can use to check the inflation of your ball. It won’t give you the PSI (or kPa), but it will be good enough to get you back out on the court.
Hold the basketball at about the level of your face.
Drop the basketball.
Let the ball bounce.
If the ball is properly inflated, it should bounce back up to around your waist level.
Another great way to tell is just by playing with the ball and dribbling it. You can often tell if it is under or over-inflated. Different players prefer various levels of inflation, so an ideal inflation level to one player may be too much or not enough to others. An interesting thing to do next time you watch a game or attend one live is to watch which players walk over to the referee before tip-off and test the ball by grabbing it and dribbling.
What’s the Best Way to Properly Inflate a Basketball
I have seen many videos and instructions out there on the internet that explain how to inflate a ball without the proper equipment. While these methods may or may not work, it is always best to use the proper equipment because you can ensure that you are inflating the basketball to the correct pressure. Using the proper equipment will also help prevent you from damaging your basketball.
Let’s take a look at what you will need to properly inflate your basketball.
What You Will Need
Inflation Needle
These are relatively cheap and can be found at almost any store that carries any type of athletic equipment. They can also be found easily online.
See the picture below if you are not familiar with what they look like.

Air Pump
There are many different types of air pumps. Below are a few types that can be used such as a hand pump, a bicycle pump or an electric pump. Basically, you need a basketball pump that can connect to the needle. Some air pumps come with built-in pressure gauges which can show you the air pressure as you are inflating the ball. You can also use an air compressor but that can be a little more complicated depending on the type of compressor and the connectors available.
Three types of air pumps.
Air Pressure Gauge (optional)
If your air pump does not have an air pressure gauge, you may want to get a separate air pressure gauge to check the pressure in your ball. Air pressure gauges can be found online or in stores, but as we mentioned above they are optional and not necessary to inflate your basketball.

Steps to Inflate Your Basketball
Step 1: Attach the inflation needle to the air pump.
How to attach the needle will depend on the type of air pump you are using. Most hand pumps made for a basketball will be threaded and you can screw needle onto the pump. If you are using a bicycle pump, it will probably have a connector with a latch (see below). You must put the needle into the connector and tighten the latch to hold the needle in place.

Electric air pumps may have the same type of latch, but a big industrial compressor may need some type of adapter and I wouldn’t recommend using an industrial compressor unless you really know what you are doing.
Step 2: Moisten the inflation needle.
Get a wet paper towel and wipe the needle to moisten it. If you don’t have a wet paper towel, you can run it underwater or even spit on it. The moisture allows the needle to slide into the valve easier and prevents damage to the valve. If the valve is damaged it can cause your basketball to leak air.
Step 3: Insert the needle into the valve.
Once the needle has been moistened, slowly insert it into the valve of the basketball until the needle is all the way in the valve.
Insert the needle into the valve of the basketball.
Step 4: Begin inflating.
If you are using a hand pump or a bicycle pump you will need to manually pump the air in. If you are using an electric pump or a compressor you can turn it on. WARNING! When using an electric pump or a compressor, monitor the inflation at all times. The ball will fill very quickly and if overfilled it can pop and destroy the ball.
Step 5: Check the air pressure.
Monitor the air pressure as you are inflating. Use one hand on the ball as you are inflating it to feel the pressure rise. If your pump has an air pressure gauge, check it regularly. If it does not use a separate gauge or check it using the bounce method described above.
Once the air pressure seems good, get out there on the court and start having fun!

Final Words
Eventually, all basketballs will need to be inflated because they will lose air over time. Fortunately, the process is fairly simple as we have shown above and the equipment needed is relatively cheap. So, if you want to have an enjoyable game of basketball, make sure your basketball is always properly inflated, then get out there and have some fun!

How to Pump a Basketball Without a Needle (3 Methods)
By Luke Updated
When shooting hoops by yourself or playing basketball with your friends, there are few things worse than your ball going flat. While it would be great if everyone had a needle and basketball pump at all times, that isn’t always the case.
I can think of several times where my friends and I had to cut a game short due to no one having a needle to inflate the ball. It’s annoying and also incredibly frustrating. Thankfully, there are a number of different ways you can pump up a basketball (whether indoor or outdoor) without needing to have a needle at all. This guide is going to look at a few of them.
Method 1: Use a Can of Compressed Air
Best to use for: If you are without a needle and pump, a can of compressed air is probably the quickest and easiest way to fill up your ball. It offers you something very similar to the needle, so getting the air in the ball will be simple. Of course, you likely need to be at home for this to work as very few people take compressed air out with them. Even then, however, it is easy enough to go to a store near where you are and get a can of compressed air for a very affordable price.
Things to prepare:
The ball
Can of compressed air (make sure it isn’t empty)
Potentially a second can if your ball is incredibly flat
How to do:
Put the end of the straw of the can into the basketball. It should fit quite easily.
Slowly start to press the trigger to allow the air to go inside the ball. Do it slowly and carefully for the best results. Once the ball is inflated to the desired amount, take out the straw and hit the courts!
Method 2: Utilize a Balloon
Best to use for: This is great for people who are at home, as most of us have some balloons lying around. It is quite easy and quick but does require the use of a few other items like a thin straw, and a paper clip or clamp. It’s not great for those who are out at a public court, as you likely don’t have balloons with you.
Things to prepare:
The ball itself
The balloon (likely more than one to be safe)
A paper clip or clamp
A thin straw or a coffee stirrer
How to do:
The first thing to do is to blow up the balloon with an ample amount of air.
Once the balloon is blown up, don’t tie it like you normally would, but use the clamp or paper clip to close it up temporarily.
Next, you need to connect the thin straw or stirrer to the balloon, and put the other into or at the air hole of the ball.
Once the clip is taken off, the air should begin to flow through the straw into the opening of the ball, inflating it.
Do this as many times as it takes to get your ball to an air level that you are comfortable with. It might take a couple of balloons.
Method 3: Go to a Bike Shop or Gas Station
Best to use for: This is a great option for you if you are out and about, and don’t have a pump, needle or anything like that at home. If you don’t have the materials for the other two methods, this could work. Going to a bike shop or gas station is a good idea as they have air pumps and might even have the attachment you need. This method is very easy and simple but could take a while to find a gas station or bike shop nearby. Also, they might not have the needle attachment so it couldn’t hurt to call ahead.
Things to prepare:
The ball
Find a safe way to get to the shop or station
Potentially pick up a basketball needle if they don’t have them
How to do:
Get to the bike shop or gas station, after calling ahead to ensure they can help you.
Use the correct attachment to inflate the ball to your liking.
Be sure to thank them if they don’t charge you. Also, consider buying something small for their kindness.
Final Words
We hope that this guide has been able to help you learn how to pump up a basketball without a needle. When trying any of the aforementioned, be sure to do it safely to protect yourself and your basketball.

Almost every ball - football, volleyball, children's, basketball, gymnastics - is suitable for use only when it is properly inflated with air. Therefore, a special pump, a needle, and sometimes even silicone grease are often sold with it. But imagine that all this is simply not at hand. How to pump up a ball without a needle? We have selected for you several effective folk methods.
Method 1: Compressor
How to inflate a ball without a needle? Contact any of the car services in your locality - workers will help you for free or for a nominal amount. Do not ignore tire shops: there will definitely be powerful compressors for pumping car tires. One thing: there is a risk of pumping the product with air, which will lead to its damage or even explosion.
Compressor - equipment from which air is released under pressure. Therefore, this is a perfect answer to the question: "How to inflate a ball without a needle and a pump?" If possible, it is recommended to carry out the procedure together: one person will turn the compressor on and off, and the second person will hold the ball and press the cord, controlling the process of air intake. The hose with the nozzle is pressed tightly against the valve, after which the device turns on at full power. It must be deactivated immediately as soon as the surface of the ball becomes hard. That's all!
We also draw your attention to the fact that many models of car compressors have special nozzles for pumping balls with air.
The tools here are among the most affordable: a bicycle pump is in almost every home, you can easily buy electrical tape in a manufactured goods store, hypermarket, a syringe in a pharmacy. How to pump up a ball without a needle in this way? Easier than simple:
Take a needle from a syringe - first of all, you need to grind its sharp tip on asphalt, brick, stone, curb or with a special knife. Too sharp, it will easily pierce the nipple, which will make the ball unusable. The best would be a needle for blood transfusion systems - it is thick, durable, does not bend.
In the second step, you make a kind of adapter from electrical tape - 10-12 layers of it are enough. They need to be wound tightly so that the air does not come out when pumping back.
How to inflate a ball without a needle? Attach the invention to a bicycle pump and proceed with the procedure.
Method No. 3: syringe
How to inflate a ball without a needle - volleyball, basketball, football? Use a large medical syringe! This is in the most extreme case, because the method is quite exhausting - you will spend about 2 hours on the procedure.
As with the second method, you will need to blunt the needle, otherwise you will damage the nipple and the ball will deflate all the time. Which syringe to choose? The more, the better:
It's really possible to inflate the ball with 20-cubic meters in 30-40 minutes.
10cc syringe will keep you busy with the ball for one to two hours.
Before starting the procedure, we recommend that you treat the nipple with silicone grease - this will protect it from damage by an imperfect needle from a syringe. It is simple to act: insert the needle into the hole, pressing the lever of the syringe, release the air. Then remove the tool, return the lever to its original position and repeat the procedure.
Method 4: Needle but no pump
We've figured out how to inflate a ball without a needle (basketball, volleyball, football, etc.) But what if you have one (or you made your own needle), and is there no pump? We offer the following instruction:
The pump will be replaced by an ordinary plastic bottle from a carbonated drink. As a last resort - a dense plastic bag without holes.
Now you need to screw the needle into the cork of the container or solder it. This will be the switch. Check that it does not let air through.
Then lubricate the ball nipple with silicone grease.
But now you need to pump air with your hands (or, if you prefer, with your feet) into our homemade pump, from where it will flow through the needle into the ball.
Other ways
Here are some more tips:
If you can't find a medical syringe, you can replace its needle with an empty ballpoint pen.
If you managed to pump up the ball just a little, then you can restore its hardness and elasticity like this: just hold it for a while in hot water. From this, the air inside the product will heat up, which will expand, which will complement the effect of jumping.
Silicone nipple grease can be replaced with machine oil.
The needle can be attached to the cap of a plastic bottle for a homemade pump with a glue gun.
Instead of a compressor, bicycle pump, bag or bottle, you can also use a regular rubber bulb.
A compressed air bottle, car spare tire or trash bag can also act as a pump.
So we have sorted out all the available ways to pump any ball with an air valve, if there was no pump and a special needle nearby. Contact a car repair shop, wield a medical syringe, build your own tool - choose what is most suitable for you.

Introduction
The ball is one of the most favorite toys for boys of all ages. There are many ball games such as football, volleyball, basketball, golf. Each game has its own ball. We know that there is air inside any ball. Therefore, the question arises: why don't all balls bounce?
Relevance: the ball is one of the most important attributes of games. Knowing the properties and types of balls helps in choosing them. Each person should have an idea about the physical phenomena and laws that he directly encounters in everyday life from childhood.
The purpose of is to study the effect of ball pressure on the height of the jump on the height of the first bounce.
Object is a basketball.
Item - air pressure in the ball.
To achieve this goal, it was necessary to solve a number of tasks:
1. Collect literature on the topic;
2. select research methods;
3. study the history of the ball, its varieties; 4. find out what sports games are played with the ball; 5. conduct an experiment explaining why the ball jumps to different heights after the amount of air in it changes;
6. draw conclusions.
Thanks to the following methods , a study was performed:
- work with Internet sources;
- work with literature;
- analysis;
- comparison.
Starting the study, we put forward the following assumption : if you release air from the ball, it will bounce lower.
Problem question of our study is: how does the amount of air in a basketball affect how high it bounces? How do basketball players determine how much air a basketball needs to have in order to play?
The novelty and practical significance of our study as a whole lies in the choice of the ball as the object of study.
1. Theoretical part.
1.1. Connection with history and science
The encyclopedia "I Know the World" says that the ball is one of the most ancient and favorite toys of all countries and peoples. In ancient Greece, it was considered the most perfect object, since it had the shape of the sun, which means (as the Greeks thought) it had its magical power. They sewed balls from leather and stuffed them with some elastic material, for example, moss or bird feathers. And later they guessed to inflate the leather ball with air. Such a ball was called "follis". Small follices were used for hand games, and large balls were used for games like football. Images of balls were found on the walls of Egyptian tombs, and during excavations of the burial places of the pharaohs, balls themselves were found, sewn from strips of leather or tree bark, and sometimes made of sandstone. The team games of the Egyptians with these items were dedicated to the gods, each team represented the interests of a group of celestials, the ball was driven into the gate with curved sticks. [1 And in ancient China they played ball, for example, by kicking it with their foot. The game eventually became a favorite folk entertainment, and in the 2nd century BC. included in the obligatory program of the solemn celebration of the birthdays of the emperor. At the same time, instead of stuffing with bird feathers and animal hair, they learned to fill leather balls with air, developed rules, and began to install gates on the playing field. The winners were honored with flowers, awarded with valuable gifts, and the losers were beaten with bamboo sticks. In ancient Japan, too, they could not do without a ball. At the imperial court, team games were held to drive the ball into the goal for a certain time (measured by the hourglass), during the throw it should not touch the ground. In Russia, the balls were different. In excavations near Novgorod, balls of various sizes were found, sewn from leather. They were played by children in the 13th century. Peasant children played with light balls made of birch bark or heavy balls tightly rolled from rags. Even information about one of the games has been preserved: they put chicken eggs in a row and knocked them out with a ball. In the Khotkovsky nunnery near Moscow, balls were sewn from soft pillows, and pebbles wrapped in birch bark were put inside - it turned out to be a ball and a rattle at the same time. By the way, the origin of the word "ball" is associated with the words "soft, pulp, crumb." That is, the ball is a soft ball.
Modern balls vary in size and purpose. Different balls are used for playing volleyball, basketball, football, tennis, water polo, rugby and other games.
Each of them has its own story. The name of the game of basketball came from the English words "basket" - "basket" and "ball" - "ball". This game was invented by D. Naismith, a sports instructor from one of the American universities, in 1891. At his direction, a large fruit basket was nailed under the ceiling of the sports hall and a ball was thrown into it. When the players got tired of climbing for the ball every time, it occurred to someone to just knock the bottom of the basket out. At first, basketball players used leather balls, and then switched to rubber ones.
The basketball must be spherical and must be the specified shade of orange with the traditional pattern of eight inlays and black stitching. The mass of the ball (officially accepted size 7) is 567-650 g, the circumference is 750-780 mm. Smaller balls are also used: in men's team games, "size 7" balls are used, in women's team games - "size 6", in mini-basketball matches - "size 5".
1.2. Definition of concepts
Working with the dictionary of S.I. Ozhegov, we learned that a ball is an object for playing a solid or full ball made of an elastic material inside, which bounces off a hard surface upon impact. [2]
Pressure is a physical quantity equal to the ratio of the force acting perpendicular to the surface to the area of this surface.
Pressure unit - Pascal (Pa). Using also other pressure units: hectopascal (hPa) and kilopascal (kPa) 1 kPa = 1000 Pa 1 Pa = 0.001 kPa 1 hPa = Pa 1 Pa = 0.01 hPa
The force arising in the body as a result of its compression and stretching (deformation) tending to return the body to its original position is called the elastic force.
According to the free encyclopedia "Wikipedia" elasticity is the property of solid materials to return to their original shape during elastic deformation. Solid objects will deform after a force is applied to them. [3]
Basketball size
First of all, when choosing a ball, you should pay attention to the size of the basketball. Size 7 means you are holding a ball that is suitable for men. Its weight can range from 567 to 650 grams. Size 6 is primarily used in the games of teenagers under 16 and adult women's teams. In addition to the circumference, its weight has also been reduced - from 510 to 567 grams. Size 5 is officially suitable for training and games of junior teams, with a weight of 470-500 grams. Of course, in your training you can use the size of the ball that you have at hand. By learning to handle a size 7, you are more likely to master a size 6 with ease. Unfortunately, the inverse doesn't always work.
2. Practical
In the practical part, we had to solve the following tasks:
- determine how the height to which the basketball bounces changes when the air pressure changes in it;
- build a graph based on the received data;
- draw conclusions based on the data obtained.
Different manufacturers measure pressure in different units, psi (pounds per square inch), bar (pressure unit approximately equal to one atmosphere), kgf/cm² (one kilogram of force per square centimeter), kPa (kilopascal). In the United States of America, the pressure inside the ball is usually measured in pounds per square inch (lb/dm 2 ).
We experimented with the amount of air in a basketball, but for measurement, we used units that are accepted in our country, namely kilopascals (kPa).
We measured the amount of air in a basketball and then used a distance sensor to measure how high the ball bounced.
Materials and equipment:
-Computer with Logger Lite installed on it;
-Go!Link adapter;
- Gas pressure sensor;
- distance sensor;
- Basketball;
- Stopper with needle, stem and tube;
-Measuring ruler.
Our experiment was carried out according to the following algorithm:
To configure the sensors for data collection, you need:
Check distance sensor connection to computer.
Set the distance sensor switch to position Normal .
Verify that the pressure transducer is connected to the adapter and that the adapter is connected to the computer.
Launch the Logger Lite program.
Open file for this experiment Air Ball (Air ball) .
Then did the following:
They took a basketball.
Zeroed the pressure sensor by pressing the Zero button on the toolbar. Next, the sensor measured the pressure in the same way as the measuring device on a bicycle pump.
Moistened the needle attached to the pressure transducer and inserted it into the ball.
Recorded data in the first line of the column "Actual pressure" of the data table.
Attached the distance sensor at a height of 2.3 m.
To collect data, did the following:
Hold the ball directly under the sensor so that the space between the ball and the sensor is about 15 cm.
Button pressed Data acquisition . Hearing the click of the sensor, they released the ball from their hands so that it hit the floor and bounced. No need to throw the ball with force!
Next, press the button View, to determine the position of the floor relative to the sensor and the distance to the ball at the top of the rebound ball #1. We recorded the obtained data in a table.
Next, we gradually reduced the pressure in the ball:
Moistened the needle attached to the pressure transducer and inserted it into the ball.
Watched the pressure reading on the screen.
Released some air.
Watch the pressure reading on the screen until it drops by 20 kPa (for the first time, the pressure will drop from 124.88 kPa to 105.79 kPa).
When the pressure dropped by 20 kPa, screwed on the connection tip so that no more air escaped.
Recorded the value in the second line of the "Actual pressure" column of the data table.
Repeat steps 3-7 for 80 kPa, 60 kPa, etc. until you get to a test where the pressure was 5 kPa.

Pins:
There is a pattern of change in the height of the rebounds with a decrease in pressure in the ball - the height of the rebounds decreases. The lowest air pressure in the ball allowed for playing basketball: 80 kPa.
Conclusion
What is basketball training without the main attribute of the game - a basketball? It is the basketball that gives us the opportunity to enjoy the gameplay in all its diversity.
Often when inflating a basketball, the question arises whether to inflate it more or less. We have to resort to the help of the Internet in search of information regarding this issue. We decided to answer the question, what is the optimal pressure should be in a basketball, since with the wrong level of pressure, the wear resistance of the chamber increases, which may simply not withstand and burst; there is a risk of injury; unpredictable flight path. The lowest air pressure in the ball allowed for playing basketball: 80 kPa.
Our study was carried out using Logger Lite software, Go!Link adapter, gas pressure sensor, distance sensor.
To achieve the goal, tasks were set that were successfully solved. To begin with, the literature on this topic was collected. Its analysis is presented in the theoretical part.
Getting to the practical part, we have identified research methods. Thanks to them, our study "The effect of air pressure on the height of the ball rebound" was carried out.
The hypothesis that we put forward at the beginning of the work was confirmed.
Having completed this study, we have developed a memo for fans of the game of basketball ( Appendix 2 ).

Inflating Basketball Instruction
Note:
The pressure in the ball is quite strongly influenced by the ambient temperature and atmospheric pressure.
Not to worry, there is a simple method that you can use to check the inflation of your ball. It won’t give you the PSI (or kPa), but it will be good enough to get you back out on the court.
While these methods may or may not work, it is always best to use the proper equipment because you can ensure that you are inflating the basketball to the correct pressure. Using the proper equipment will also help prevent you from damaging your basketball.
You can also use an air compressor but that can be a little more complicated depending on the type of compressor and the connectors available.
If you are using an electric pump or a compressor you can turn it on. WARNING! When using an electric pump or a compressor, monitor the inflation at all times. The ball will fill very quickly and if overfilled it can pop and destroy the ball.
While it would be great if everyone had a needle and basketball pump at all times, that isn’t always the case.
Of course, you likely need to be at home for this to work as very few people take compressed air out with them. Even then, however, it is easy enough to go to a store near where you are and get a can of compressed air for a very affordable price.
It’s not great for those who are out at a public court, as you likely don’t have balloons with you.
If you don’t have the materials for the other two methods, this could work. Going to a bike shop or gas station is a good idea as they have air pumps and might even have the attachment you need. This method is very easy and simple but could take a while to find a gas station or bike shop nearby. Also, they might not have the needle attachment so it couldn’t hurt to call ahead.
When trying any of the aforementioned, be sure to do it safely to protect yourself and your basketball.

In ancient Greece, it was considered the most perfect object, since it had the shape of the sun, which means (as the Greeks thought) it had its magical power. They sewed balls from leather and stuffed them with some elastic material, for example, moss or bird feathers. And later they guessed to inflate the leather ball with air. Such a ball was called "follis". Small follices were used for hand games, and large balls were used for games like football. Images of balls were found on the walls of Egyptian tombs, and during excavations of the burial places of the pharaohs, balls themselves were found, sewn from strips of leather or tree bark, and sometimes made of sandstone. The team games of the Egyptians with these items were dedicated to the gods, each team represented the interests of a group of celestials, the ball was driven into the gate with curved sticks. [1
included in the obligatory program of the solemn celebration of the birthdays of the emperor. At the same time, instead of stuffing with bird feathers and animal hair, they learned to fill leather balls with air, developed rules, and began to install gates on the playing field. The winners were honored with flowers, awarded with valuable gifts, and the losers were beaten with bamboo sticks. 
In the Khotkovsky nunnery near Moscow, balls were sewn from soft pillows, and pebbles wrapped in birch bark were put inside - it turned out to be a ball and a rattle at the same time. By the way, the origin of the word "ball" is associated with the words "soft, pulp, crumb." That is, the ball is a soft ball. 
At first, basketball players used leather balls, and then switched to rubber ones. 
Its weight can range from 567 to 650 grams. Size 6 is primarily used in the games of teenagers under 16 and adult women's teams. In addition to the circumference, its weight has also been reduced - from 510 to 567 grams. Size 5 is officially suitable for training and games of junior teams, with a weight of 470-500 grams. Of course, in your training you can use the size of the ball that you have at hand. By learning to handle a size 7, you are more likely to master a size 6 with ease. Unfortunately, the inverse doesn't always work.

Next, the sensor measured the pressure in the same way as the measuring device on a bicycle pump. 
We recorded the obtained data in a table.

We decided to answer the question, what is the optimal pressure should be in a basketball, since with the wrong level of pressure, the wear resistance of the chamber increases, which may simply not withstand and burst; there is a risk of injury; unpredictable flight path. The lowest air pressure in the ball allowed for playing basketball: 80 kPa.
