Question

The bar is equipped with ventilators which exchange the smoke-air
mixturē with fresh air. Cigarette smoke contains 4% carbon monoxide and
a prolonged exposure to a concentration of more than 0.012%
The bar has a floor area of 20 m by 15 m, and a height of 4 m. It is estimated
that smoke enters the room at a constant rate of 0.006 m/min, and that the
ventilators remove the mixture of smoke and air at 10 times the rate at which
smoke is produced. The problem is to establish a wise time to leave the bar.
That is, sometime before the concentration of carbon monoxide reaches the
lethal limit.
(a) Starting with a word equation and compartmental diagram, formu-
late the differential equation for the changing concentration of carbon
monoxide in the bar over time.​
