Video: How Winds are formed? Wind results from the movement of air due to atmospheric pressure gradients. Wind flows from regions of higher pressure to regions of lower pressure. The larger the atmospheric pressure gradient, the higher the wind speed. The Sun is the key source of winds on the earth’s planet. Winds are mainly…
The blades of a wind turbine are affected by four forces: drag, lift, centrifugal, and gravitational forces. Drag Force on Wind Turbine Drag forces are caused by the air molecules that hit the surface of the blade facing the wind. A major component of the drag force acts in the direction that is parallel to…

How much energy content is in the wind and how much power a wind turbine can generate from a given wind speed can be explained by the following formula So, the power generated by a wind turbine depends upon air density, rotor disc area, and wind speed. Usually, we consider air density as constant thus…
