Problem 12.13

The performance characteristics of a certain centrifugalpump having a 9-in.-diameter impeller and operating at 1750 rpmare determined using an experimental setup similar to that shown inFig. 12.10. The following data were obtained during a series of testsin which z2 z1 = 0, V2 = V1, and the fluid was water.Q (gpm) 20 40 60 80 100 120 140p2 p1 (psi) 40.2 40.1 38.1 36.2 33.5 30.1 25.8Power input (hp) 1.58 2.27 2.67 2.95 3.19 3.49 4.00Based on these data, show or plot how the actual head rise, ha, andthe pump efficiency, , vary with the flowrate. What is the designflowrate for this pump?
