wind turbine power output formula
Betz''s law
In high wind speed, where the turbine is operating at its rated power, the turbine rotates (pitches) its blades to lower C p to protect itself from damage. The power in the wind increases by a factor of 8 from 12.5 to 25 m/s, so C p must fall accordingly, getting as low as 0.06 for winds of 25 m/s. Understanding the Betz results
