In the figure below, a pump delivers a useful head of 300 m to the water. If the difference in elevation between the two water bodies is 150 m, determine the power that the pump adds to the water knowing that the pipe length is 600 m, the pipe diameter is 15 cm, the pipe is made of stainless steel and the valve is a gate valve that is fully opened. State your assumptions and show a step-by-step procedure of your solution. Pump D
