In a test of the centrifugal pump shown in Fig. below, the following data are taken: py =100 mmHg (vacuum) and pz = 500 mmHg (gage). The pipe diameters are D1 = 12 cm and Dz = 5 cm. The flow rate is 180 gal/min of light oil (SG =0.91). Estimate (a) the head developed, in meters, and (b) the input power required at 75 percent efficiency
