2. Starting with the general solution to the Indoor Air Quality (IAQ) mass balance model (Equation 7.64), apply the correct assumptions and solve the IAQ model for: a. Pollutant concentration at steady-state conditions (Equation 7.63). b. Pollutant concentration for a conservative pollutant when initial concentration is zero and ambient concentration is zero (Eq. 7.65). 2.
