Why does a desert cooler cool better on a hot dry day? |
|
Answer» On a hot dry day ,the temperature is high and humidity is low. The rate of evaporation increases with increase in temperature and decrease in humidity. A desert cooler functions on the principle of evaporation. The water takes heat from the hot desert cooler and evaporates. The evaporation of water cools the pads and the circulating water. As a result, the incoming air also gets cooled down Answer: Adesert coolercoolsbetter on a hot dry daybecause on ahot dry daytemperature is high and humidity is less which helps inbetterevaporation. Due to the higher rate of evaporation it givesbetter coolingeffect. |
