A Pelton wheel with an efficiency of 85% is used to produce hydroelectric power from flow of water behind a dam with an elevation head of 420 m. The average radius of the wheel and its angular velocity are 2.0 m and 220 rpm, respectively. This turbine works at its optimum rotation rate (which produces maximum power). The turning angle of the buckets is ? = 165° and nozzle diameter is given as 8.00 cm. a. Calculate volumetric flow rate...

A Pelton wheel installation uses a water jet of 75mm diameter to drive a wheel with the buckets on a diameter of 0.9m. The deflection angle of the buckets is 160 o .The relative velocity of the water is reduced by 12% while moving across the buckets. The rotational 8 speed is 320rpm, the total pressure behind the nozzle is 0.7Mpa and the velocity coefficient of the nozzle is 0.98. Determine 5.1 the hydraulic power developed by the wheel, 5.2...
