Question 1

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

💡 Hint: Recall the structure of the dispersion formula discussed in class.

Question 2

True or False: The Gaussian dispersion model can only apply to a single emission source at a time.

  • True
  • False

💡 Hint: Consider whether the model's limitations were discussed.

Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Remember to adjust distances appropriately for each source.

Question 2

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.

💡 Hint: Consider how wind behavior changes around large objects.
