14-60E A centrifugal pump is used to pump water at 77°F from a reservoir whose surface is 20.0 ft above the centerline of the pump inlet. The piping system consists of 67.5 ft of PVC pipe with and ID of 1.2 in and negligible average inner roughness height. The length of pipe from the bottom of the lower reservoir to the pump inlet is 12.0 ft. There are several minor losses in the piping system: a sharp edged inlet (KL = 0.5 ), two flanged smooth 90° regular elbows (KL = 0.3 each), two fully open flanged glove valves (KL = 6.0 each), and an exit loss into the upper reservoir (KL = 1.05). The pump's required net positive suction head is provided by the manufacturer as a curve fit: NPSHreq = 1.0 ft + (0.0054 ft/gpm^2)Q^2, where volume flow rate is in gpm. Estimate the maximum volume flow rate (in units of gmp) that can be pumped without cavitation.
