A kerosene heater that emits 500 mg/hr of carbon monoxide (CO) is used to heat a 200 m³ home with 0.5 air changes per hour (ach), where volumetric air flow rate Q = volume x ach, in m³/hr. The house temperature is heated to stay at 20°C. (a) Assuming that CO is a conservative substance, determine the steady state CO concentration (in mg/m³) in the home. (b) Given that the National Ambient Air Quality Standard (NAAQS) for CO is 9 ppm, is the standard exceeded?
