The pelton wheel

WebbPelton wheel. Old Pelton wheel from Walchensee Hydroelectric Power Station, Germany. A Pelton wheel is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. WebbAnswer (1 of 3): Pelton wheel is a kind of impulse turbine. As in case of impulse turbine pressure throughout turbine is constant and equal to atmospheric pressure, so only energy available for turbine is kinetic energy of fluid. So higher is the kinetic energy, higher is the turbine output final...
