[TowerTalk] Wind Force

[Ellen M.]

Hello Tower Talk,
I had a question pertaining to the equation, F=PA where F is the windforce, P is wind pressure(lb./ft^2), and A is antenna wind area (ft^2).  P=0.004(or 0.00256) V^2. I was wondering how the 0.004 converts the mph(V) into lb/ft^2(P) for wind pressure. Any ideas would really help me out. 
 
Thank you,
Ellen M.
