Your Questions About Wind Generator Blades
James asks…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 alladmin answers: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
