The density, ρ =
The wind blows steadily. So, the K.E. =
The power generation is the time rate of the kinetic energy which can be calculated as follows:
Power =
Regarding that . Then,
Power → Power = constant x
Since, is constant for both the sites and the area is the same as same winf turbine is used.
For the first site,
Power,
For the second site,
Power,
