I am trying to do a simple wind pressure calculation on an antenna, but I am confused about how to do it. I see conflicting information on towertalk archives and various ham vendor sites. Let me see
Richard, It depends on which specification you use. Correctly applied you should get the same answer either way. I think the newer specs carry the 2/3 drag coefficient for round members in the wind p
The drag force on a cylinder perpendicular to the wind (and other forms) is given by: Drag = Cd X 1/2 X density of air X area X velocity squared. (D = Cd*.5*rho*A*V^2) Cd, coefficient of drag, is a f
No. Part of the reason is there is no really "simple" answer is that at least two "correct" ways exist for answering the question: a pure "physics" answer and an applied "engineering" answer. Either
Here is a quote from the YS manual: Somewhere on the YS web site, there is a justification, such as it is, for using this obsolete formula. Applying it to the example I gave would give an effective a
Another thing that may not be so obvious is that one should only be using the RS 222-C coefficients (2/3 & 0.004) with basic wind speeds read from a RS 222-C wind zone map, not with basic wind speed
