Water from a reservoir is pumped over a hill through a pipe 90 cm in diameter, and a pressure of 200 KPa is maintained at the summit where the pipe is 90 m above the reservoir. The quantity pumped is 1.40 m3/s and by reason of friction there is a head loss of 3 J/N between reservoir and summit. If the pump is 90% efficient, determine the input power of the pump.

5. Water from a reservoir is pumped over a
hill through a pipe 90 cm in diameter,
and a pressure of 200 KPa is
maintained at the summit where the
pipe is 90 m above the reservoir. The
quantity pumped is 1.40 m3/s and by
reason of friction there is a head loss of
3 J/N between reservoir and summit. If
the pump is 90% efficient, determine
the input power of the pump.
