The pump is used to pump water from a low reservoir to a high reservoir through a total
length of 800 m of pipe 15 cm diameter. The difference between the water levels in the
reservoirs is 8 m. Neglecting all losses except friction and assuming f= 0.004, find the rate of
flow between the reservoirs. Also determine the power input to the pump.
