To convert the wind speed to the force acting on a surface, follow these steps:
Multiply the air density with the square of the wind speed.
Divide this value by 2 to get the wind's dynamic pressure:
dynamic pressure = 0.5⋅air density⋅wind speed²
Multiply the surface's area with the sin of the angle it makes with the horizontal (θ) to get its effective area:
effective surface area = area⋅sin(θ)
Multiply the dynamic pressure with the effective surface area to obtain the force the wind applies on the surface:
wind load = dynamic pressure⋅effective surface area
