What is the absolute pressure after the cylinder gas is compressed?
Question restated below for reference:
The gauge pressure of a pneumatic cylinder reads 100 psi when the volume is 40 in³.
The cylinder is compressed until the gauge reads 150 psi. Assume standard atmospheric
pressure (14.7 psi).What is the absolute pressure before the cylinder gas is compressed
?
114.7 psi
164.7 psi
135.3 psi
150 psi
