F=MA
The F in the equation is the wind pressure
the mass is the air volume per unit density, which is practicaly a constant
the A is the object it is hitting, such as a house
How does that change exponentially??
A in that formula is Acceleration.
For using the actual sustained wind speed expected (were we to actually determine it) :
Force, F = A x P x Cd
A = The projected area of the item
P , Wind pressure (Psf), = .00256 x V^2 (V= wind speed in Mph)
Cd , Drag coefficient, = 2.0 for flat plates. For a long cylinder (like most antenna tubes), Cd = 1.2.
Note the relationship between them is 1.2/2 = .6, not quite 2/3.
This is the force on a discreet constant section. I.E. A length of tubing or some other such member that is part of a structure. The Force per unit area would be found by setting the area to 1.
