Question: A small water pump is used in an irrigation system. The pump takes water in from a river at 10C, 100 kPa at a rate

A small water pump is used in an irrigation system. The pump takes water in from a river at 10C, 100 kPa at a rate of 5 kg/s. The exit line enters a pipe that goes up to an elevation 20 m above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 10C.
Find the required pump work.
