The wind pressure is the amount of force exerted by the wind per unit area of the blades and is given by P 12 1 c 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

Sep 12 2011nbsp018332The vertical turbines are great when in turbulent air as the direction of the wind does not matter. This is great for places with buildings and such in the area and close to ground installations. They do have a problem self starting at low wind speeds but with a little kick start it is possible.

Wind shear is the change in wind direction andor wind speed over a specific horiontal or vertical distance. Atmospheric conditions where wind shear exists include areas of temperature inversions along troughs and lows and around jet stream. When the change in wind speed and direction is pronounced quite severe turbulence can be expected.
