A centrifugal pump having outer diameter equal to two times the inner diameter and running at 1200rpm works against a total head of 32m. The velocity of flow through the impeller is constant and equal to 3m/s. The vanes are set back at an angle of 30° at the outlet. If the outer diameter of the impeller is 600mm and width at outlet is 50mm, determine (a) vane angle at inlet, (b) work done per second by impeller, and (c) manometric efficiency.

Plz answer in 30min A Francis radial-flow turbine has a runner inlet radius of 2.75 m and its outlet radius is 1.85 m. The runner blade widths are 0.9 m and 2.93 m at the inlet and outlet, respectively. The runner must rotate at 150 rpm to turn the 60-Hz electric generator. The wicket gates turn the flow by angle 35° from radial at the runner inlet, and the flow at the runner outlet is to have angle 20° from radial for proper flow through the draft tube.
