**Chat Online**## Power calculations for Pelton turbines

The Pelton turbine is designed to produce maximum power when the peripheral speed is 1/2 of the water jet speed. Therefore the power transmitted to the turbine wheel is 50% of the incoming water jet power. This is because the water jet is reversed by the wheel cup design 180 degrees back towards its source.

**Chat Online**## How To Calculate Power Output Of Wind Windpower Engineering

Jan 26, 2010018332Although the calculation of wind power illustrates important features about wind turbines, the best measure of wind turbine performance is annual energy output. The difference between power and energy is that power (kilowatts [kW]) is the rate at which electricity is consumed, while energy (kilowatthours [kWh]) is the quantity consumed.
