Wind turbine - Wikipedia

Efficiency. Conservation of mass requires that the amount of air entering and exiting a turbine must be equal. Accordingly, Betz's law gives the maximal achievable extraction of wind power by a wind turbine as 16/27 (59.3%) of the rate at which the kinetic energy of the air arrives at the turbine. The maximum theoretical power output of a wind machine is thus 16/27 times the rate at which ...
