About Wind power generation formula

The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3.

The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3.

The wind power formula is given as, = 0.5 × 1.23 × 1256 × 1000 P = 772440 W. Wind energy describes the process by which wind is used to produce electricity.

P = ρ A v3 / 2 = ρ π d2v3 / 8 (1) where P = power (W) ρ = density of air (kg/m3 ) A = wind mill area perpendicular to the wind (m2) v = wind speed (m/s) π = 3.14. d = wind mill diameter (m).

Wind turbines generate power as an incoming mass of air transfers its energy into the turbine as it slows down. The formula for kinetic energy is 0.5 x mass x velocity^2.

Question: Calculate the power output of a wind turbine under these conditions using the Wind Energy Formula. Solution: Use the formula P = ½ ρ A v³. P = 0.5 × 1.225 kg/m³ × 30 m² × (10 m/s)³
