Question 1.
What is the steady-state assumption in dispersion modeling?
Show hintHide hint
Think about what happens if the pollution source does not change.
Question 2.
Define dispersion in environmental science.
Show hintHide hint
Consider how smoke behaves after leaving a chimney.
3Question 3.
What does the steady-state assumption entail?
- Concentration changes with time
- Concentration remains constant over time
- Only spatial concentration is uniform
Show hintHide hint
Reflect on how pollution behaves at a fixed location.
4Question 4.
Is mass conservation a fundamental principle in dispersion modeling?
- True
- False
Show hintHide hint
Think about what happens to water in an aquarium.
Question 5.
A factory emits pollutants at a rate of 500 kg/hour. Given constant wind speed and steady-state conditions, calculate the concentration at a distance of 100 meters downwind, considering the dispersion coefficient. Assume you have necessary constants.
Show hintHide hint
Remember the basics of Gaussian distribution.
Question 6.
If a pollutant dispersion is skewed due to changing wind directions, describe the implications for the accuracy of the Gaussian model and suggest a method to address this.
