7) Water is pumped at the rate of 275 m3/min from a lake into a tank on a hill 75.0 m above 7) the lake. (1 m3 = 1000 L) What power (in kW) must be delivered by the pump? b. What horsepower rating must this pump motor have? What is the increase in potential energy of the water each minute? Assuming 25% of the pump power is lost, what power (in kW) must be delivered by %3D a. C.
