At the power station, a Pelton wheel produces 1260kW under a head of 610m. The loss of head due to pipe friction between the reservoir and nozzle is 46m. The buckets of the Pelton wheel deflect the jet through an angle of 1658, while relative velocity of the water is reduced by 10% due to bucket friction. The bucket/jet speed ratio is 0.46. The bucket circle diameter of the wheel is 890mm and there are two jets. Find the theoretical hydraulic efficiency, speed of rotation of the wheel, and diameter of the nozzle if the actual hydraulic efficiency is 0.9 times that calculated above. Assume nozzle velocity coefficient, Cv = 0.98

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
