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.
