A pump steadily draws water through a pipe from a reservoir at a volumetric flow rate of 22 gallons per minute. At the pipe inlet, the pressure is 14.7 psi, the temperature is 68 °F, and the velocity is 12 ft/s. At the pump exit, the pressure is 38 psi, the temperature is 68 °F, and the velocity is 44 ft/s. The pump exit is located 38 ft above the pipe inlet. Ignoring heat transfer, determine the power required by the pump in BTU/s. Acceleration of gravity is 32.0 ft/s².
