A centrifugal pump is installed in a pipeline between two reservoirs. The pump is required to produce a flow rate of 2,500 gpm (gallons per minute) in moving water from the lower reservoir to the upper reservoir. The water surface elevations of the two reservoirs are separated by 104 feet, and the pump operates at an overall efficiency of 78.5 percent. Determine the required power input (in kW) to the motor. (Assume that pipeline losses are negligible.)
