Question: A simple circuit is shown in Fig. During no-load extension, the pressure measurements were
P1 = 150 psi
P2 = 120 psi
The cylinder bore is 1.5 in., and the rod diameter is 0.625 in. Find the friction force (lbf ) for this cylinder. The friction force is defined as the force required to overcome the friction due to the piston seals sliding along the inside of the cylinder and the rod seals sliding on the rod.
