Water from a reservoir is pumped over a hill through a pipe 30 cm in diameter, and a pressure of 250 KPa is maintained at the summit where the pipe is 100 m above the reservoir. The quantity pumped is 0.20 m3/s and by reason of friction there is a head loss of 15 J/N between reservoir and summit. If the pump is 80% efficient and its motor is 90% efficient, determine the input power of the pump.
