Water, p=1.94 slugs/ft³ and v=0.000011 ft²/s, is pumped between two reservoirs at 0.2 ft³/s through 400 ft of 2-in-diameter pipe and several minor losses, as shown in Figure. The roughness ratio is e/d =0.001. Compute the pump horsepower required. If the efficiency is 80%, what is the electrical power?
