Sails Power Conversion To Hp

Hi all

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

Classe Diecipiedi

area of triangle sails

Classe Diecipiedi

area of 4 side sails

Classe Diecipiedi

Hope these one can help someone ( all measure are in centimeters 100cm=1 meters=0,33 ft)
