A small water pump is used in an irrigation system. The pump takes water in from a river at 10oC, 100 kPa at a rate of 4.5 kg/s. The exit line enters a pipe that goes up to an elevation 18 m above the pump and river, where water runs into open channel. Assume the process is adiabatic and that the water stays at 10oC. Determine (a) The required pump power.
