The pump shown below delivers a head of 75 m (hpump) to the water. The total length and the diameter of the pipe are 150 m and 20 cm, respectively. This is a very new and very smooth pipe. There are four 90° threaded regular elbows and one angle valve along the pipe. Determine the power (in kW) that the pump adds to the water. The difference in elevation between the lake and the reservoir is 60 m. Elbow Elbow Reservor Elbow GElbow Vole LAKE
