A pump is used to deliver water from a large reservoir toanother large reservoir that is 20 m higher.The inlet of the pipe is submerged in the one reservoir andthe exit is just above the surface of the otherreservoir.

If the friction head loss inthe 200-mm-diameter, 4-km-long pipelineis 2.5 m for every 500 m of pipelength, determine the required power output of the pump so the flowis 0.5 m3/s.

Answer is not 196 kW
