A pump lifts 60°F water from a stream to a reservoir whose surface is an unknown distance above the free surface of the stream. The suction pipe (from thestream to the pump) is 250 ft of 8-in Schedule 40 steel pipe, while the discharge pipe (from the pump to the reservoir) is 2250 ft of 8-in Schedule 40 PVC (plastic)pipe. The pump consumes 150 hp and has an estimated efficiency of 85%. The suction inlet of the pump is located 2.5 ft below the surface of the stream, whilethe discharge port of the pump is located at the same elevation as the surface of the stream. A differential manometer connected to the suction and discharge sidesof the pump measures a pressure difference of 128 psi. Consider the friction loss in the piping (using the Darcy-Weisbach equation), but neglect other (minor)losses.FlowReservoirPump2.5 ftStream
