Kinetic wind pressure

It's raining here, so what's better than some hard calculus to warm up the day ? Here are the numbers Luigi sent me this morning; we hope they are usefull to you too ( no warranty !). We're using square meters and Kilograms, we apologize with "imperial" users. Wind speed is considered till 25 knots, you should reef if more.

We really hope in a good weather window this week-end, to stop theory and start practice, cause you know, theory and practice are equivalent, in theory, but not in practice.

Fair winds :-)
