WebThe power in a flow. The relevant calculation for the power contained in a flow through a rotor is: Power (in watts) = ( V^3 ) x 0.5 x p x A. V is the water flow speed in metres per second – this then needs to be cubed (raised to the power of 3). p is the density, which is about 1000 kg per cubic metre for water. WebIt is estimated that turbines are able to convert over 90% of water’s kinetic energy into mechanical energy. A hydroelectric turbine is made up of a stationary part called a distributor or stator, and a wheel or impeller.
