The common factor of wind energy is W=1/2 (ρsV3)
In the formula: ρ——air density (kg/m2); V——wind speed (m/s); S ———Cross-sectional area (m2). S=1/4*π*D*D, D is the diameter of the wind wheel.
Bring in the value: W=1/8*ρ*π*D*D*V*V*V=1/8*1.293*3.14*1.2*1.2*8*8*8=374 . 1714
According to Bates theory: the maximum wind energy utilization rate does not exceed 59.3%. This data is obviously false. It is impossible for the wind energy utilization rate to exceed 100%, and let me tell you, this is not possible. It's just theoretical. If the wind energy utilization rate of current wind turbine manufacturers can reach 30%, it would be great. Most of them are less than 20%.
