Question

The maximum power coefficient of the wind turbine is cp max=0.42 and the rotor radius is 40m

Answer 1

Answer:

The Betz limit is the theoretical maximum efficiency for a wind turbine, conjectured by German physicist Albert Betz in 1919. Betz concluded that this value is 59.3%, meaning that at most only 59.3% of the kinetic energy from wind can be used to spin the turbine and generate electricity.
