A single-acting reciprocating pump of 25 cm ram diameter and 40 cm crank radius operates at a speed of 50 rpm. Calculate the volumetric efficiency of the pump if the actual discharge is 32.07 I/s

A double-acting reciprocating pump with a crank radius of 30 cm and a piston diameter of20 cm operates at a speed of 75 rpm. The piston rod diameter is 2.5 cm. Determine the discharge and the power required to run the pump if the static head is 8.5 m and the overall efficiency is 87%. Neglect the effect of water slip.
