Water reservoir is pumped over a hill through a pipe 450 mm in diameter and a pressure of 98.08 kPa is maintained in the summit water discharge is 30 m above the reservoir. The quantity pumped is 0.50 m3/s. rrictional losses in the discharge and suction pipe of the pump is equivalent to 1.5 m head loss. The speed of the pump is 800 rpm, what amount of energy must be furnished by the pump in kW?
