Power from Wind (wind turbine equation)
The power available in the wind is given by:
P = 0.5ρAv3
where:
P = power in W,
ρ = ('rho') is the density of the air in kg m-3,
A = the area through which the wind is passing (e.g. the area swept by a wind turbine rotor),
v = the speed of the air in m s-1.
The base units on each side of the equation are:
(kg × m2 × s-3)
Note:
Modern wind turbines can generate up to 5 MW of electricity and have sizes in excess of 100 m
