A pump, for which the characteristic curve is shown below, is used to pump water from a canal into a dam. The pump is mounted 2.0 m above the water level. There is a 50 mm PVC pipe connected to the suction side of the pump, and a 40 mm PVC pipe connected to the discharge side. The total length of pipe on the suction side is 8 m, and there is a strainer (K = 20), a non-return valve, a 90° elbow and a fully open gate ball valve in the suction line. Another fully open gate valve, and two 90° elbows are mounted in the discharge line. The total length of the discharge line is 60 m, and the discharge pipe outlet is 4 m above the pump.

A self-priming centrifugal pump is used to pump water at 25°C from a reservoir whose surface is 2.2 m below the centerline of the pump inlet. The pipe is PVC pipe with an ID of 26.0 mm and negligible average inner roughness height. The pipe length from the submerged pipe inlet to the pump inlet is 2.8 m. There are only two minor losses in the piping system from the pipe inlet to the pump inlet: a sharp-edged reentrant inlet (KL = 0.85), and a flanged smooth 90° regular elbow (KL = 0.3). The pump’s required net positive suction head is provided by the manufacturer as a curve fit: NPSHrequired = 2.2 m + [0.0013 m/(Lpm)2 ]V.2 , where volume flow rate is in Lpm. Estimate the maximum volume flow rate (in units of Lpm) that can be pumped without cavitation.
