3. (15 points) At night when electricity demand is low, river water is pumped into a storage tank on a 150 m high hill, and during the daytime, the water is used to turn turbines to meet the peak power demand. Find the pump power required to transport 50 m/min using an 800 m long, 80 cm inner diameter pipe. The pump efficiency is 85%, the specific gravity and viscosity of water are 1 and IcP, respectively, and the friction loss is 10m H.O
