Question 1.
What is the significance of measuring wind speed at stack height?
Show hintHide hint
Think about how pollutants spread.
Question 2.
What would stability class 'A' indicate?
Show hintHide hint
Consider what conditions would make the air actively mix.
3Question 3.
Which class indicates very unstable atmospheric conditions?
- A
- D
- F
Show hintHide hint
Remember the types of stability classes.
4Question 4.
True or False: Sigma parameters are not affected by atmospheric stability.
- True
- False
Show hintHide hint
Think about how different classes change dispersion.
Question 5.
Analyze a case where a new factory is to be constructed. Different stability classes are present during different times of the day. How would you determine the optimal time for emission testing?
Show hintHide hint
Think about the time of day when the atmosphere varies the most.
Question 6.
A new model predicts that under specific environmental conditions, sigma z increases significantly. Discuss the implications for local air quality.
Show hintHide hint
Link increased vertical dispersion with air quality outcomes.
