Question 1.
Define steady-state assumption in the context of pollutant dispersion.
Show hintHide hint
Think about what happens to concentrations over time at a fixed point.
Question 2.
What does the Gaussian model depict regarding pollutant concentration?
Show hintHide hint
Recall the shape of the distribution curve.
3Question 3.
What does the steady-state assumption imply?
- Concentration changes over time
- Concentration remains constant over time
- Concentration is irrelevant
Show hintHide hint
Think about concentration stability over time at fixed points.
4Question 4.
True or False: The Gaussian dispersion model assumes pollutants spread symmetrically in all directions.
- True
- False
Show hintHide hint
Visualize the shape of the dispersion model.
Question 5.
A factory emits pollutants at a rate of 100 grams per second. Assuming a constant wind speed of 3 meters per second and applying the Gaussian dispersion model, calculate the expected concentration at a distance of 100 meters.
Show hintHide hint
Don't forget to incorporate the plume parameters in your calculations!
Question 6.
Considering an area where wind direction changes frequently, how should environmental models adapt when using the Gaussian dispersion model?
Show hintHide hint
Think about how changes in wind direction could affect dispersion patterns.
