Question: what is the mathematical equation for wind power?
Answer: How to calculate power output of wind. k = 0.000133 A constant to yield power in kilowatts. (Multiplying the above kilowatt answer by 1.340 converts it to horse- power [i.e., 1 kW = 1.340 horsepower]). The rotor swept area, A, is important because the rotor is the part of the turbine that captures the wind energy.
