Calulating the wind power.

I have been doing some math regarding the power of the wind.
The formula i found is
Power output = 0,5 * swept area * air density * v^3
where 0,5 is th betz value = the difference between the power of the wind and what can be generated as electricity.
Air desity= 1,23 since i live close to the sea.
Wind velocity m/s
and swept area 1.44 ( i have decided to make it 1200mm in diameter since that gives alot more drag-force .
