A pump is installed in the pipeline between reservoirs A and E as shown in the figure below. Water surface elevations for Reservoirs A and E are 25 ft and 40 ft, respectively. The diameters and lengths of pipes are shown in the figure. The Hazen- Williams coefficients for all pipes are 120. Entrance loss from reservoir A is 0.5 and exit loss from reservoir E is 1.0. The discharge for the pipeline is 10 cfs. The efficiency of the pump is 0.85. Determine the horsepower required for the pump.
