Q.10. Mention different clocking mechanisms. [2]
Answer
The maximum theoretical efficiency (power coefficient) of a wind turbine is given by the Betz limit, Cp_max = 16/27, approximately 59.3%, derived from actuator-disk momentum theory as the maximum fraction of the kinetic energy in an air stream that any idealized wind turbine can extract, regardless of its specific blade design; real turbines achieve somewhat lower practical efficiencies (typically 35-45%) due to additional aerodynamic, mechanical, and electrical losses beyond this ideal theoretical limit.
