Why does a desert cooler cool better on a hot dry day?

Question 1. Why does a desert cooler cool better on a hot dry day?
Answer: 
A desert cooler cools better on a hot dry day because on a hot dry day temperature is high and humidity is less which helps in better evaporation. Due to the higher rate of evaporation it gives better cooling effect.
