Question 1.
What does the steady-state assumption imply about pollutant concentrations?
Show hintHide hint
Think about what it means for something to be steady.
Question 2.
Define mass conservation in your own words.
Show hintHide hint
Consider the importance of mass balance.
3Question 3.
What is a steady-state assumption in pollution modeling?

Show hintHide hint
Think about what 'steady' means in physics.
4Question 4.
True or False: Boundary conditions do not impact pollutant dispersion.
- True
- False
Show hintHide hint
Consider the shape and limits of the model.
Question 5.
Given a steady pollutant emission from a source, derive the concentration equation in a fully developed Gaussian plume.
Show hintHide hint
Start with the basic mass flow relationships in a steady system.
Question 6.
Evaluate how varying the wind speed affects the dispersion of pollutants in a modeled environment.
Show hintHide hint
Think about how wind carries and diffuses the emissions.
