Question 1.
What does the steady state assumption imply?
Show hintHide hint
Think about time vs. location.
Question 2.
What is mass conservation?
Show hintHide hint
How does this relate to pollutants in the air?
3Question 3.
What does the steady state assumption indicate about pollutant concentration?
- It changes over time
- It remains constant over time
- It only varies by place
Show hintHide hint
Think of a fixed-time scenario.
4Question 4.
True or False: The emission rate has to be variable for the steady state assumption to hold.
- True
- False
Show hintHide hint
Consider what happens when emissions change.
Question 5.
Consider a factory emits pollutants at a rate of Q. If the cooling temperature changes, altering emission rates, how would you approach the modeling of this pollutant?
Show hintHide hint
What model can handle varying emissions?
Question 6.
A plume expands in three dimensions due to environmental factors. How would you mathematically represent the maximum concentration in this dispersion model?
Show hintHide hint
Think about how spread affects concentration visualizations.
