Using the single-zone box model interactive tutorial for indoor air pollutant dynamics, answer the following questions.
- What parameters control the location of the peak in time?
- How long does it take for pollutant to be completely removed from the space?
- For what parameter values does the pollutant concentration reach an asymptote (i.e., a plateau)? What physical conditions are occurring when the concentration reaches the asymptote?
- How does the height of the asymptote change with each parameter?
- How does the rate of increase in pollutant concentration depend on each parameter?
- How does the rate of decrease in pollutant concentration depend on each parameter?
- How does filtration affect the pollutant level for different room volumes? Why is this the case?
- Multiply the emission rate by the duration of the source. What does this number represent? What units does it have?
- Divide the number you got in the previous question by the volume of the space. What does this number represent? What are its units? How does it compare to the peak value observed on the plot?
