Question 1.
What is the emission rate of SO₂ used in the model example?
Show hintHide hint
It's mentioned early in the problem statement.
Question 2.
What is the significance of the stack height in dispersion modeling?
Show hintHide hint
Think about how the height of the stack might influence the spread of emissions.
3Question 3.
What is the formula used in the Gaussian dispersion model for estimating concentration?
- A. C = (Q/2πσyσz)e^-(y²/2σy²+z²/2σz²)
- B. C = Qσyσz(1+y²+z²)
- C. C = (Q/πσy^2)e^-(x²/2σy²)
- D. C = (σyσz)/Q
Show hintHide hint
Recall the structure of the dispersion formula discussed in class.
4Question 4.
True or False: The Gaussian dispersion model can only apply to a single emission source at a time.
- True
- False
Show hintHide hint
Consider whether the model's limitations were discussed.
Question 5.
Given three pollution sources with emission rates of 100, 200, and 150 grams per second at various distances, calculate the combined concentration at a receptor point using the Gaussian model.
Show hintHide hint
Remember to adjust distances appropriately for each source.
Question 6.
A community plans to site a new industrial facility. Based on the surrounding area’s wind patterns and existing buildings, determine optimal stack height to ensure safe dispersion.
Show hintHide hint
Consider how wind behavior changes around large objects.
