Hello. I am designing a windmill and I would like to know what the wind pressure is on it under varying conditions.

I need an equation for this.

The surface area of the windmill that will be facing the wind will be "A" .
A can vary from 2 square meters to 9 square meters.

The height that the windmill will be above the level flat ground will be "H" .
H can vary from 3 meters to 30 meters.

The wind speed will be "S" .
S can vary from 8 Kilometers per Hour to 160 Kilometers per Hour.

The mass density of the air will be "p" .
p can vary from: 1.168 kg/m3 {At standard ambient temperature and pressure (25 °C and 100 kPa) and 0% humidity}
to whatever it is at 100% humidity.

I want a generic formula where I can plug in these all in and get the wind load on my windmill (not including the pole that supports it).

Thanks.
