The power generated by wind turbine goes approximately like $P={1\over 2}C_p\rho A v^3$ Where $\rho$ is the density of air, $A=\pi r^2$ is the area swept by the blades, $v$ is the velocity of the wind and $C_p$ is a power conversion factor that is around 0.3-0.4 for the best wind turbine designs and will probably be on the order of 0.1 for your rotor. ...
