A 'three cylinder' reciprocating pump, has a cylinder with a diameter of 250 mm and a stroke of 500 mm. The pump is needed to flow water with a capacity of 0.1 m³/sec at a head of 100 m. Friction losses are estimated at 1 m in the suction pipe, and 19 m in the distribution/delivery pipe. The water flow speed is 1 m/s. The total efficiency of the pump is 85% and the slip percentage is 3%. Determine: a) Pump rotational speed, n (Hint: use two equations, Q, and % Slip) b) Power required to drive the pump, SHP Remember: H=(Z-Z)+(PP)/+(-)+H
