paddle blade design
(OP)
Dear Friends:
I need a formula to find the force applied to a surface knowing the speed of the flow of water and the area of the blade.
Best Regards

Hope this helps.
RE: paddle blade design
Force = Pressure x Area
Where r is density of fluid, v is velocity of fluid...Area
Cd = shape coefficient
Very simplistic approach, as there are other things to consider also
RE: paddle blade design
Pressure should not have Cd term P = 1/2.r.v^2
Force = Cd.pressure.area
