(1 point) We did a lot of work with material balances in water, and I mentioned that the same knowledge could be applied to air quality modeling. Here's an example: You live 2km downwind of the refinery (with the PM concentration you calculated from the plume equation) and want to know how this new facility would affect you if you open your window. What would the concentration of PM in your house be if you left the windows open all day (steady state) if your house has a volume 2000m³, you open windows such that the air entering and leaving your house is flowing at rate 0.5m³/s, and the particles settle out of the air in a manner approximating first order decay with rate k=0.01/s? dM Hints: Before we had: = = QiCi - QoCokCV dt Eqn. 12-27 states the same thing slightly differently dC V- =QCo + E-QC - KCV dt Outdoor concentration, Co = Assume there is no source µg/m³ of PM inside your house Which variable are we solving for: Relationship at steady state: Indoor PM Concentration: -µg/m³
