Calculate the hourly energy cost for pumping river water at 288.706K, from a river to a hilltop, through a 0.458 ft ID pipeline at an average velocity of 8.1818 m/hr(mph) the pipeline is 0.8523 miles long and discharges into the atmosphere at a level of 0.5682 miles above the level of water in the river. The pump is 70 percent efficient and the local energy cost is 7 cents per KWH. assume the friction losses inside the pump to be 1.0779kJ/kg.
