The wind pressure is the amount of force exerted by the wind per unit area of the blades and is given by P = 1/2 1 c ρ v 2. Where c is a constant and equals 1.0 for long flat plates. The force of the wind against the windmill blade is based on the wind pressure multiplied by the area of the blade facing the oncoming flow.

Oct 31 2014 Efficiency When the wind blows on the blades of a HAWT all of them contribute to energy production. When wind blows on a vertical axis turbine only a fraction of the blades generate torque while the other parts merely ‘go along for the ride’. The result is comparably reduced efficiency in power generation.
