Question 1.
Define the Steady-State Assumption.
Show hintHide hint
Think about how time affects concentration measurements.
Question 2.
What does neglecting the dx term achieve?
Show hintHide hint
Consider how the x dimension would complicate calculations.
3Question 3.
What does the steady-state assumption imply in pollutant modeling?
- Concentrations change over time
- Concentrations remain constant over time
- Only emissions are constant
Show hintHide hint
Recall the meaning of steady in the context of concentration.
4Question 4.
True or False: Neglecting the dx term can simplify calculations.
- True
- False
Show hintHide hint
Consider what happens when you remove a variable from an equation.
Question 5.
If a source emits pollutants at a constant rate, how would you model the variability in concentration at different points in a city?
Show hintHide hint
Consider using statistical methods to derive averages and standard deviations.
Question 6.
Describe how you would approach modeling pollutant dispersion if the emissions varied unpredictably over time.
Show hintHide hint
Think about adaptability in modeling approaches and how averages can help.
