The gauge on your pump, if you have one.
7 1/2 and 8 1/2 psi
I pumped up a basketball to 60 PSI, at about 55 it started making crackling noises, when I got to 60 PSI the crackling noise was constant and within 2 seconds of reaching 60 PSI the ball exploded. The ball was a Wilson Optima Rubber Basketball .
Yes, a basketball filled beyond its capacity will burst or explode.
For NBA regulation basketballs, the requirement is between 7.5 and 8.5 psi. Your basketball may vary, and if it does, the packaging should state how much psi should be used. Source: http://www.livestrong.com/article/84284-basketball-official-size-weight/
About 8 PSI
7.5 to 8.5 psi
A concrete strength of 3500 PSI should be just right for a basketball court.
Tire gauge, and some basketball and bicycle pumps.
You will need a gauge and you would check the Pressure on the low side port. Take the PSI reading when the compressor is on and the clutch is engaged. The correct PSI is determined by the current ambient temperature and you can find a PSI chart on the website listed below.
A Football is harder. They are pumped to 13 (12.5 to 13.5) PSI in the NFL while a basketball in the NBA is 8.5 PSI. PSI is pounds per square inch. i believe they were looking for the difficulty levels of the two sports rather than the pressure of the ball. in that case it is strictly a matter of opinion eVEN IF IT WAS MORE MATTER OF OPINION fOOTBALL IS WAY MORE CONTACT THAN BASKETBALL THEREFORE FOOTBALL IS WAY HARDER
psi on a 2000 Chevy truck, place the key in the on position the fuel pressure should be between 50- 60 psi....The General Motors test for this is the pressure should NOT drop more than 6-8 psi during the first 10 secounds, if it does check you fuel lines for leakes at the filter and check the check ball in the fuel system
