Question: a pump needs to move water from a lower reservoir...

Question details

A pump needs to move water from a lower reservoir to an upper reservoir at a rate of 600 cfs through a 9,000 ft long, 6-ft diameter pipeline (f = 0.03). For a 1,500 ft change in water surface elevation between the lower and upper reservoirs, compute the needed power input to the pump assuming a pump efficiency of 75% and that minor losses are negligible. In addition, compute the needed power input to the corresponding motor assuming the motor efficiency is 85%. Report your answers in horsepower.
