About 8 PSI
== == The proper air pressure in an NBA basketball is around 7 1/12 to 8 1/2 lbs.
The more air pressure within a basketball, the more capable it is to bounce efficiently, rather than a basketball with little air pressure.
The answer depends on the pressure when the air is let out of the basketball.
The pressure inside the stadium. WHAT DO YOU THINK!!!
Yes. A full basketball with medium to high pressure will clearly bounce higher than a flat basketball with low pressure.
NBA regulation requires to be 7.5 to 8.5 pounds in air pressure.:)
The pressure from the air inside of it
NBA rules state a basketball's air pressure should be between 7.5 and 8.5 pounds.
Air pressure in a room is less than that of a basketball since it does not crush the basketball. Think of the crushed can experiment. If you empty a soda can, flip it upside down, put it (carefully) on a boiling pot of water, the can will fill with hot air. You then transfer the can on a container with cold water (making sure the opening of the can is covered with the cold water). You should see the can implode or at least the outside air pressure (since it's greater than that of the air pressure in the can) crush the can. Opposite of the basketball.
