change the data to metric units and solve for parts a and b

change the data to metric units and solve for parts a and b The system of Figure 8-52 has a hydraulic cylinder with a suspended load W. The cylinder piston and rod diameters are 2 in and 1 in respectively. The pressure relief valve setting is 750 psi. Determine pressure p_2 for a constant cylinder speed if W = 2000 lb W = 0 (load is removed)

Pressure p2 will be = 750
