1. water is pumped at the rate of 1400 gallons per minute through a centrifugal pump operating at a speed of 1750 rpm. the impeller has a uniform blade height, b, of 2 in. with r1 = 1.9 in. and r2 = 8.0 in., and the exit blade angle β2 is 23°. assume ideal flow conditions and that the tangential velocity component, vθ1, of the water entering the blade is zero (α1 = 90°.) the temperature of the water is 80 °f. 1a. what is the tangential velocity component, vθ2, at the exit? 1b. what is the ideal head rise, hi? 1c) what is the power, whp, transferred to the fluid?
