I asked ChatGPT the question:
"how can I calculate the wind pressure in Pascals if I know the wind
speed and surface area?"
It returned:
"Wind pressure can be calculated using the formula: P = 0.613 x V^2 x A,
where P is the wind pressure in Pascals, V is the wind speed in meters
per second, and A is the surface area in square meters. This formula
assumes that the wind speed is measured at a height of 10 meters and
that the wind is hitting a flat, smooth surface."
This AI stuff is interesting ... it's often quicker to ask the bot than
it is to do a Google search.

I am attempting to size a Trylon Super Titan tower and noticed something in the
Canadian catalogue that has me stumped.
The CSA Standards (Class 1 with 10mm Ice, Class 2 with 25mm Ice and Class 3
with 25 mm Ice) are shown with what I believe are specified survival rates in
Pa, which I assume is Pascals. For example, the allowable antenna areas
indicated are shown for 350 Pa/450 Pa/550 Pa for each CSA standard.
In contrast, the Titan line in the Canadian Catalogue does indicates allowable
antenna areas for 75/85/100 mph wind speed and does not utilize Pascals.
Does anyone know if there is a simple conversion of Pascals to mph (or kph) ?
From my research, it does not seem to be a simple answer ... hopefully I am
wrong.
I am looking at going with a JK Mid-Tri-40 and the 72' Trylon Titan does not
provide enough capacity so I believe that a 70' Super Titan will be required.
Any comments are appreciated.
