A centrifugal pump with backward-curved blades has the following measured performance when tested with water at 20°C: Q, gal/min | 0 | 400 | 800 123 115 108 101 1200 | 1600 | 2000 | 2400 Н, ft 93 81 62 P, hp 30 36 40 44 47 48 46 (a) Estimate the best efficiency point and the maximum efficiency. (b) Estimate the most efficient flow rate, and the resulting head and brake horsepower, if the diameter is doubled and the rotation speed increased by 50 percent.
