1. [TowerTalk] Equivalent wind load to square ft (score: 1): Author: Cqtestk4xs@aol.com; Date: Thu, 27 Oct 2011 09:56:15 -0400 (EDT); A friend of mine is thinking of putting up some wind generators and has asked for my advice. The only information he can give me for the wind load is 300# at 100 MPH. I know that makes sense to some,; /archives//html/Towertalk/2011-10/msg00429.html (6,910 bytes)

Re: [TowerTalk] Equivalent wind load to square ft (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Thu, 27 Oct 2011 07:34:35 -0700; What they have done is calculate the total load at 100 mi/hr. A rule of thumb is that wind load in pounds is Area(sq ft)* windspeed (mi/hr)^2/391 So, his windload at 50 mi/hr would be 75 lbs.

There are modifiers beyond Cd (drag/shape) that need to be taken into account which modify the force due to heig; /archives//html/Towertalk/2011-10/msg00437.html (11,302 bytes)

Re: [TowerTalk] Equivalent wind load to square ft (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Thu, 27 Oct 2011 17:13:58 -0700; Oh yeah.. there's a whole lot more than just tower face loading, Cd variations with Reynolds number, etc. Any "real" design needs to take all that stuff into account.
