A well tuned car emits about 0.1 g CO per minute while a poorly tuned car emits 10g CO per minute. Presume the vehicle is parked in a closed garage with no air exchange of dimensions 8 m by 5 m by 3 m. A lethal concentration of CO is 0.1 g CO/m3.
1) Explain how long would it take before a lethal concentration is reached with a well tuned car? Define how long for the poorly tuned car?
2) State the mass balance equation for this solution using simply variables and eliminating terms that are zero.
