Give reason why wet clothes dry faster under the fan
Answers
The rate of evaporation is directly proportional to the velocity of wind, the fan increase the velocity of wind over the wet clothes and as soon as the water vapours rise up they are displaced by the high velocity winds again and again creating an empty space for more vapours to rise up and occupy the space resulting in increased rate of evaporation from the clothes.Therefore more the velocity of wind,more is the rate of evaporation and less the velocity of wind,less is the rate of evaportaion.
The rate of evaporation is directly proportion to the velocity by wind. Wet clothes take longer time to dry on a humid day because on a humid day , clothes take longer to dry and sweat from our body does not evaporate easily , making us feel very comfortable....
