If a wind blowing at 40 mph exerts a force of 50 lb on a surface of 500 square feet, how much force will a wind of 80 mph place on a surface of 2 square feet?
---------------
The most commonly used method is the force is a function of the square of windspeed.
The wind is 2x --> 4x the pressure.
50*4*(2/500) = 0.8 pounds
