Top Q&A For: How to Calculate Wind Speed and Rotor RPM

If the wind speed doubles what happens to the theoretical wind power?

When wind speed doubles, the theoretical wind power increases by eight times. This is because wind power is determined by the equation "P = 0.5 x rho x A x V^3". Where A is the size of the turbine... Read More »
