An inflated basketball has a gauge pressure of 9.0 lb/in^2.
What is the actual pressure inside the ball?
Its actual pressure is 9.0lbs/inch, measured by the air guage. Its absolute pressure is 9.0+14.1 lbs/in^2
If you are in physics, I wonder why you are using the Old English system of units.
To find the actual pressure inside the ball, you need to add the atmospheric pressure to the gauge pressure. The atmospheric pressure can vary, but for most everyday purposes, it is around 14.7 pounds per square inch (psi) at sea level.
So, to find the actual pressure inside the ball, you can use the formula:
Actual pressure = Gauge pressure + Atmospheric pressure
Given that the gauge pressure is 9.0 lb/in^2 and the atmospheric pressure is approximately 14.7 lb/in^2, you can substitute these values into the formula:
Actual pressure = 9.0 lb/in^2 + 14.7 lb/in^2
Adding these values together, the actual pressure inside the ball is:
Actual pressure = 23.7 lb/in^2
