In a wind powered generator, can someone give me a formula to calculate wind speed, blade length, etc.?

If I know what Kw output I am looking for, what wind speed etc. is required to achieve this.
Thanks to all

Available electric power = .6125 x D x A x V3 x E

where:
D = air density ratio at elevation x density ratio at temperature
A = swept area in square meters (blade length² x 3.14)
V = wind speed in m/s
E = blade efficiency (obtained from manufacturer or dealer)
(To convert miles-per-hour to meters-per-second, multiply by 0.447.)

A density calculator can be found here. You will have to provide the information for your area.
