QUESTION:
Problem 124P
A vertical, frictionless piston–cylinder device contains a gas at 500 kPa. The atmospheric pressure outside is 100 kPa, and the piston area is 30 cm2. Determine the mass of the piston.
ANSWER:
Solution 124P
The pressure of the gas, atmospheric pressure and the area of the piston are given. We need to calculate the mass of the piston.
In this case, the force of the pressure exerted by the gas will be equal to atmospheric-pressure force and the weight of the piston.
