You have been asked to design a similar pump from the existing one. The existing pump works for water is of impeller diameter equals 6 cm and its performance data is shown here when working at 1725 rpm. The newly design pump is for a refrigerant (R-134A) and it must produce 450 cm of head at 1600 rpm when working at its best efficiency. One of your colleagues did preliminary analysis and develop the performance curves in dimensionless form for...

A 6.5-in pump, running at 3500 rpm, has the measured performance for water. If this pump is rescaled in water to require 20 hp for break horsepower input at BEP point while running at 3000 rpm, determine the appropriate (a) impeller diameter; (b) flow rate; and (c) efficiency for this new condition. 50 100 150 200 250 400 450 Q, gal/min: H, ft: 201 200 194 189 156 300 350 181 169 80 81 198 64 139 72 29 50...
Q4. A pump draws water from a large reservoir and delivers it to another reservoir whose water surface is 10 m higher than the pump centreline and that the pump is 1.5 meter above the suction reservoir. The total suction and deliver pipe used is 21.1 m in length, 9 cm in diameter and has a Darcy friction factor f0.0339. The pump operates at 750 rpm and its characteristic performances are given in table below: Q (m3 s H (m)15...
