Check this box for calculating the theoretical wind power per unit of surface (W/m2) of an undisturbed wind streaming (i.e. without any rotor).
The power which can be extracted from the wind depends from the wind turbine features and, according to the Betz law, will not exceed the 59% of the theoretical power.
The theoretical wind power is calculated under the following assumptions:
- 1) Air density is 1.225 kg/m3
- 2) No power coefficient applied (as stated above)
- 3) Input wind speed units are m/s
