A single-acting reciprocating pump of 25 cm ram diameter and 20 cm crank radius delivers a discharge of 200 I/s with a volumetric efficiency of 97%. What is the operating speed of the pump? Knowing that when the suction head is 3.0 m and the overall efficiency of the pump is 85%, the power required to run the pump is 25 hp, find the maximum delivery head of the pump. What is the force on the ram during the delivery stroke?
