If 2000 ft³ of air is crossing an evaporator coil and is cooled from 80°F to 60°F, what would be the volume of air in ft³ exiting the evaporator coil?

Given :

If 2000 ft³ of air is crossing an evaporator coil and is cooled from 80°F to 60°F.

To Find :

The volume of air in ft³ exiting the evaporator coil.

Solution :

We know, relation between initial and final temperature and volume is given by :

Here, temperature is in Kelvin .

We know, Kelvin temperature is given by :

Putting F = 60° F,

Putting F = 80° F,

Putting all values, we get :

Hence, this is the required solution.

answer: the answer is a
