Question

The 92% efficient pump receives 30 hp form a 95% efficient electric motor. The pressure rise across the pump is 1500 psi and all elbows are 90degree with a K-factor of 0.75. Cylinder i has a piston diameter of 6 inches and a rod diameter of 2 in. Cylinder 2 has a piston diameter of 4 in. and a rod diameter of 1.5 in. pipi information is supplied below. The hydraulic oil has a kinematic viscosity of V = 0.001 ft^2/sec and a specific weight of 7 = 50 lb/ft^3. What is the maximum forte F_1 that can he supported by cylinder I in extension if it is known that F_2 = 5 kips?
