Question 1.
What is the steady-state assumption in the Gaussian dispersion model?
Show hintHide hint
Think about how concentration behaves over time.
Question 2.
What does a bell curve represent in the context of pollutant concentration?
Show hintHide hint
Consider how concentrations differ from the center to the edges.
3Question 3.
What does the steady-state assumption entail?
- Concentration changes with time
- Concentration remains constant over time
- Concentration decreases over time
Show hintHide hint
Focus on what 'steady-state' implies in terms of time.
4Question 4.
True or False: The shape of a Gaussian dispersion curve is symmetric.
- True
- False
Show hintHide hint
Consider the standard shape of a bell curve.
Question 5.
A factory emits 100 kg/h of a pollutant. If the wind speed is 5 m/s, calculate the expected concentration 100 meters downwind, considering the dispersion coefficients.
Show hintHide hint
Remember the relationship between emission rates and distance in the model.
Question 6.
Explain how seasonal wind patterns could potentially alter the assumptions of the Gaussian dispersion model in urban environments.
Show hintHide hint
Think about how consistent wind direction might change with the seasons.
