The pelton wheel can be used for the power production which rotates at a speed of 12 m/s where as water coming at a speed of 30 m/s. the water coming out at a rate of almost 0.2 m^3/s with an deflection angle of 130 degrees we may assume the complete flow is ideal so what is the approximated power that can developed? Please solve correctly, If not sure do not post and do not do plagirism...

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...

Pu. 9. In Pelton wheel installation a small auxiliary nozzle is often fitted, from which a jet of high pressure water can f the buckets, thus acting as a brake and bringing the wheel quickly to reset. Estimate the time required to stop the wheel by the brake nozzle under the following conditions: diameter of brake nozzle = 7 cm, head at the nozzle = 475 m, original velocity of...
