WebbWind Energy and Power Calculations. Print. The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3. Power = Watts. ρ (rho, a Greek letter) = density … WebbIn this equation, p is the pressure in kPa and T is the temperature in kelvin. The power in the wind is then P w = 1 2 ρAu3 = 1.742pAu3 T W(4) ... Wind Energy Systems by Dr. Gary L. Johnson November 21, 2001.
