8 in. dia 500 +50% 55 -60 63 -99 400 7 65 Problem 1 (35 points): (a) [30 points] The 7-in-diameter centrifugal pump operating at 1200 rpm having the performance characteristics as shown is geometrically similar to the 10-in-diameter pump operating at 1000 rpm. For peak efficiency, predict discharge, actual head rise, shaft horsepower and 300 actual power of the 10-in-diameter pump? Working fluid is water. b) [5 points] A pump is designed to work at speed = 1500 rpm, ha = 300-ft, and Q = 10000 gpm. What type of pump should be selected? 63 60 6 30 I 200 15 1508 30 100 25 2015 0 NPSHR 10 on on NPSHR, ft 0 40 80 120 160 200 240 280 320 Capacity, gal/min
