To solve this problem it is necessary to apply the concepts related to the heat exchange of a body.
By definition heat exchange in terms of mass flow can be expressed as
Where
Specific heat
= Mass flow rate
= Change in Temperature
Our values are given as
Specific heat of air
From our equation we have that
Rearrange to find 
Replacing
Therefore the exit temperature of air is 53.98°C
