Question

why wind speed is directly proportional to evapouration

Answer 1

The speed at which air flows over the surface of water affects the rate at which the water evaporates. As the wind blows, it sweeps away airborne water particles that are in the air. The humidity of the air in the region of this evaporation is reduced, which allows more water molecules to dissipate into the air. Wind can also change the vapor pressure by moving air about rapidly, thereby causing it to expand. This process creates room for extra water vapor and evaporation will continue to occur while the wind is blowing.......
