Wind area of mast.

[Gene.Smith@mailhost.bellhow.com (Gene Smith)]

I want to calculate the effective wind area of
a 2" diameter mast that is 72" long.

Therefore 72" X 2" = 144 sq.in = 1 sq.ft.

The calculation above would be accurate if the
mast were square.  But because it's round
isn't there a constant I neet to multiply the
result by.

If anyone know this constant please let me know
and also tell me its source such as EIA-222, etc.

Thanks.
