How is your week end?
Weel i was wondering the formula to calculate the power of a sail in a certain wind
(resulting in kw or hp)
As far as i know/found is for example
10 knots wind
= 5,4m\s x 1,28 kg m cube (air density) x surface exposed as square meters= kg of force on that given area, with wind perpendicular to it (90°)
How to convert kg/ mq in equivalent hp or kw?
Does someone knows a site where you impout all the data, and it calculates it? Also as heeling force, ecc?
I would like to share this page where you can calculate the sail center by yourself
area of triangle sails
area of 4 side sails
Hope these one can help someone ( all measure are in centimeters 100cm=1 meters=0,33 ft)
