Q1. A centrifugal pump impeller has 0.4m inlet diameter and 0.7 m external diameter. The pump run at 980 rpm, and the entry of the pump is radial. The velocity of flow through the impeller is constant at 3.9 m/s. The impeller vanes are set back at angle of 46° to the outer rim as shown in figure 1. Calculate: a. The vane angle at inlet of pump. b. The velocity direction of water at outlet. c. The work done by the water per kg of water. 46° Co V2 Ca U Figure 1: Velocity triangle at impeller outlet and inlet
