Formula
P = 0.5 × ρ × π × r² × v³ × Cp (air density ρ=1.225 kg/m³)
- Wind Turbine calculates its result from Rho, R, V, Cp. It uses the formula P = 0.5 × ρ × π × r² × v³ × Cp (air density ρ=1.225 kg/m³). Change any input to recalculate the result instantly.
- The main inputs are Rotor Diameter, Average Wind Speed, Efficiency. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Wind Turbine
Inputs
- Rotor Diameter: 30
- Average Wind Speed: 8
- Efficiency: 0.35 Cp
Using Rho = 2, R = 3, V = 4, Cp = 5, the calculated result is 9047.7868423386.
