A centrifugal pump running at 3500 rpm pumps water at a rate of 0.01cu. m./sec. The water enters axially, and leaves the impeller at 5m/s relative to the blades, which are radial at the exit. If the pump requires 5kW, and is 67% efficient, estimate the basic dimensions (impeller exit diameter and width).

In a medical water treatment station, there is a centrifugal pump. The pump delivers a flow rate of 0.003 m3/s. The pump radius is 0.3 m. The water enters axially and leaves the impeller relative to radial blades at the exit. Theoretically using Euler turbomachine equation, what should be the rotation speed for the pump to develop a head of 9 mH2O? Give your answer in rotation per minutė (rpm).

The mean radius of an axial flow reaction turbine is 2.6 ft. and the axial velocityis 25 ft./s. The wicket gates are turned at an angle such that relative velocity at theinlet flow makes an angle of -45° with the blade velocity. The wheel and hub radiiare 3.6 ft. and 1.6 ft., respectively. The turbine rotates at 240 rpm. If water leaves theblade in a purely axial direction, calculate H and all relevant angles.Ans: H=81.87 ft.; α1=31.8°; β2=20.93°
