A small water pump is used in an irrigation system. The pump takes water in from a river at 50 F, 1 atm at a rate of 10lbm/s. The exit line enters a pipe that goes up to an elevation 60 ft above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 50 F. Find the required pump works?
