Question 548120: In a hydraulic cylinder, the air pressure varies inversely as the volume. If the pressure is 50 punds per square inch (lb/in.^2) when the volume is 40 cubic inches (in.^3), what will the pressure be when the volume is 20in.^3? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! In a hydraulic cylinder, the air pressure varies inversely as the volume. If the pressure is 50 punds per square inch (lb/in.^2) when the volume is 40 cubic inches (in.^3), what will the pressure be when the volume is 20in.^3?
-----------
P = k/V
PV = k
--------
50*40 = k = 2000
---------
what will the pressure be when the volume is 20in.^3?
P*20 = 2000
P = 100 psi
