Question 1.
What is mass balance?
Show hintHide hint
Think about how substances enter and leave a system.
Question 2.
Define an Eulerian model.
Show hintHide hint
Recall the fixed reference frame concept.
3Question 3.
What principle does mass balance follow?
- Rate out equals reactions
- Rate in minus rate out
- Total emissions
Show hintHide hint
Think about what actually changes in a system.
4Question 4.
True or False: Lagrangian models are fixed in one place.
- True
- False
Show hintHide hint
Recall the definitions of model types we've discussed.
Question 5.
A factory releases 500 kg of pollutant continuously. If 300 kg is removed by natural processes and 100 kg are converted through reactions, calculate the amount remaining in the surrounding area after 5 hours of steady monitoring.
Show hintHide hint
Remember to subtract the rates appropriately.
Question 6.
Discuss the implications of turbulent winds on dispersion modeling in urban areas. How could this affect pollutant concentration predictions?
Show hintHide hint
Think about how wind patterns affect climate and air quality.
