The room receives 10,000 ft3/min of fresh air containing 0.04% CO2. After 30 minutes, the CO2 level rises to 0.12%. To calculate the CO2 level at 12:00 PM, a differential equation model is used. The CO2 generation rate is calculated to be 8.53 ft3/min. Solving the model at 300 minutes gives a CO2 level of 0.1253%. To keep the CO2 level below 0.1%, the required fresh air flow is 14,217 ft3/min.
