Question
A centrifugal pump is used to pump water between two reservoirs as shown in the bellow figure. The dimensions and minor loss coefficients are provided in the figure. The pump rotates at 1600 rpm, the water inters the impeller normal to the blades and exits at an angle of 45° from radial. The inlet radius is 5.5-in, at which the blade width is 7.09-in. The outlet radius is 8.66-in, at which the blade width is 6.7-in. The volume flow rate is 23-cfm. Assuming 100 percent efficiency, calculate the net head produced by this pump in cm of water column height, the required brake horsepower in W and calculate the pump capability to pump water to upper reservoir. Reservoir z3-2, = 22.0 ft (elevation difference) D = 1.20 in (pipe diameter) KL. entrance = 0.50 (pipe entrance) KL. valve I = 2.0 (valve 1) KL. valve 2 = 6.8 (valve 2) Reservoir Valve 2 KL elbow = 0.34 (each elbow-there are 3) KLe L = 124 ft (total pipe length) e =0.0011 in (pipe roughness) = 1.05 (pipe exit) exit Pump Valve 1
