1.25 cfs of water at 70°F are pumped from the bottom of a tank through 700 ft of 4-in steel pipe. The line includes a 50-ft rise in elevation, two 90° elbows, a wide-open gate valve, and a swing check valve. The inlet pressure is 50 psi and a working pressure of 20 psi is needed at the end of the line. What is the necessary power developed by the pump (kW) to accomplish this task?
