Question

Look at the given figure and suggest in which of the vessels $A,B,C$ or $D$ the rate of evaporation will be the highest? Explain.

Answer 1

The rate of evaporation increases with the increase in surface area and wind speed. The surface areas of vessel $C,A$ and $D$ are similar but the wind speed is greater above the vessel $C$ because of fan, hence the rate of evaporation will be highest in the vessel $C$.
