Question

What is the formula for max power in wind extracted

Answer 1

Cp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59) ρ = Air density, lb/ft3. A = Rotor swept area, ft2 or π D2/4 (D is the rotor diameter in ft, π = 3.1416) V = Wind speed, mph. k = 0.000133 A constant to yield power in kilowatts.

Answer 2

$\boxed{Explained\:Answer}$

______________________________

Cp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59) ρ = Air density, lb/ft3.

A = Rotor swept area, ft2 or π D2/4 (D is the rotor diameter in ft, π = 3.1416) V = Windspeed, mph.

k = 0.000133 A constant to yield power in kilowatts.
