Calculate a rate of cooling down of air from 80 c to 5c show calculation. give an answer in cubic meters per minute and cfm.

Explanation:

Given that,

Rate of cooling of air

Initial temperature= 80°C

Final temperature = 5°C

We need to calculate

Using newton's law of cooling

Where,

Here,

= 25°C  (surrounding temperature)

dt = 1 minute

Put the value into the formula

Hence, This is the required answer.
