Question

A pump delivering 230 lps of water at 30C has a 300-mm diameter suction pipe and a 254-mm diameter discharge pipe as shown in the figure. The suction pipe is 3.5 m long and the discharge pipe is 23 m long, both pipe's materials are cast iron. The water is delivered 16m above the intake water level. Considering head losses in fittings, valves, and major head loss. a) Find the total dynamic head which the pump must supply. b)It the pump mechanical efficiency is 68%, and the motor efficiency is 90%, determine the power rating of the motor in hp.
given that: summation of K 
gate valve = 0.25
check valve=3
90 degree elbow= 0.75
foot valve= 0.78
