Power = 0.5 x Swept Area x Air Density x Velocity[sup]3[/sup]
from Calculation of Wind Power - Wind
In the Wikipedia is a big mistake or inaccuracy
Call it what you think.
Now why is that:
Kinetic Energy = Mass x 0.5 x Velocity2 It is certainly true.
But when it comes to the calculated mass is no longer referred to as:
Mass / sec (kg / s) = Velocity ( m / sec ) x Area ( m2 ) x Density (kg/m3 )
In my opinion, if we count the mass, we must indicate the volume
of the cylinder, which is in addition to its surface and its length
Here, due to an error or a" shortcut calculations" assume that the length of the cylinder is equal to 1.
But it is not always true mass depends also on the length of the cylinder, because they can be 50 meters.
Of course, if you will take part in the formation of energy.
Even in a new traditional windmill blade width can have two meter, and now the model is invalid.
* But because the masses are Surface x L x Density. Always.
Well, where we have L ?
By the way. What has to calculate the speed of her weight?
