wind power profile





The change in the power available in the wind due to changes in the wind speed or velocity profile; the wind power profile is proportional to the cube of the wind speed profile.

For air density of 1.225 kg/m3, corresponding to dry air at standard atmospheric pressure at sea level at 15° C.
The formula for the power per m2 in watts = 0.5 × 1.225 × v3, where v is the wind speed in m/s.
