The penstock supplies water from a reservoir to the Pelton wheel with a gross head of 516 m. One third of the gross head is lost in friction in the penstock. The rate of flow of water through the nozzle fitted at the end of the penstock is 1.8 m3/s. The angle of deflection of the jet is 165º. Determine the power (MW) given by the water to the runner. Take speed ratio = 0.45 and Cv = 1.0. Use ρ = 998 kg/m3. Round off your final answer to two decimal places.

Question

The penstock supplies water from a reservoir to the Pelton wheel with a gross head of 516 m. One third of the gross head is lost in friction in the penstock. The rate of flow of water through the nozzle fitted at the end of the penstock is 1.8 m³/s. The angle of deflection of the jet is 165º. Determine the power (MW) given by the water to the runner. Take speed ratio = 0.45 and C_v = 1.0. Use ρ = 998 kg/m³. Round off your final answer to two decimal places.
