A kerosene stove that produces 0.8 g/hr of carbon monoxide (CO) is used in a closed room with a volume of 200 m3. Fresh air enters the room at the rate of 40 m3/hr and stale air leaves at the same rate. Assuming complete mixing and that carbon monoxide is a conservative pollutant (i.e., does not undergo decay), determine the steady state CO concentration

Answer :

Answer:

20 mg/m3

Explanation:

Given -  

S = 0.8 g/hr

Q = 40m3/hr

V =200 m3

As we know, the steady state CO concentration is given by  

Css = S/Q  

= 0.8/(40m3/hr)

= 800 mg/hr/(40m3/hr)

= 20mg/m3
