Enter the radius, wind speed, air density, and efficiency factor into the calculator to determine the total power output from the wind.

## Wind Power Formula

The following equation is used to calculate wind power.

P = π/2 * r² * v³ * ρ * n
• Where P is the power in watts
• r is the radius of the turbine
• v is the velocity of the wind moving through the turbine
• p is the air density (1.2 kg/m^3)
• n is the efficiency factor (typically 40%)

## Wind Power Definition

Wind power is defined as the total amount of energy per unit of time that a wind turbine can generate through the kinetic energy of moving air.
