Wind pressures at various Beaufort scales

[Trevlyns]

Hello guys

I’m trying to establish the wind pressure generated at various Beaufort strengths – e.g. at force 4 the pressure is about one pound per square foot. Does anyone have figures for the lesser and greater forces? I’m trying to devise a mechanism to automate the angle of attack on the vane of a wingsail according to wind strength.

Your input, as always, is greatly valued and appreciated!
