Question

why is it that on increasing the wind speed the rate of evaporation increase

Answer 1

because wind speed is directly proportional to the rate of evaporation
with increasing the wind speed the particles of the water moves away with the wind
decreasing the amount of water vapour in the air

Answer 2

Answer:

The evaporation rate increases with increase in speed of air flows on the water surface.

Airborne particles are swept away by wind blows. The evaporation on this region of water surface, the humidity of the air is reduced, allowing the water molecules to get dissipated into the air.

Wind is also affected by the changing the pressure of the vapor by quickly moving the air around, which cause expansion. This process produces space for evaporation and forms water vapors.
