Question

What is the effect of wind speed on evaporation?

Answer 1

Evaporation: Evaporation is a process in which a phase transition occurs from the liquid phase to the gaseous phase by absorbing heat.

• The rate of evaporation depends upon the temperature, surface area, and humidity.
• When the air is humid it means the water vapour content in the air is high. So, the intake capacity of air decreases.

Effect of wind speed on evaporation:

• When wind speed increases, it blow away the water vapour present in the air.
• Due to a decrease in water vapour content air humidity of air decreases.
• So, due to decrease in the humidity of air, the rate of evaporation increases.

Hence, the rate of evaporation increase with increase in speed of wind.
