Question 6: Solve this question and present your solution approach to your lecturer. A self-priming centrifugal pump is used to pump water at 25C from a reservoir whose surface is 2.2m below the centerline of the pump inlet. The pipe is PVC pipe with an inner diameter of 24mm and negligible average inner roughness height. The pipe length from the submerged pipe inlet to the pump inlet is 2.8m. 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: NPSH required =2.2m+[0.0013m/(Lpm)2]V2, where the volume flow rate is in liters per minute (Lpm). Estimate the maximum volume flow rate (in units if Lpm ) that can be pumped without cavitation
