Question 1

What does the term 'Gaussian Dispersion Model' refer to?

  • A device for measuring air quality
  • A mathematical model for estimating pollutant concentration
  • A chemical process used in industrial emissions

💡 Hint: Think about how we mathematically represent air pollution.

Question 2

True or False: A higher stack height generally leads to better dispersion of pollutants.

  • True
  • False

💡 Hint: Consider what happens to emissions when they are released from greater heights.

Challenge Problems

Push your limits with challenges.

Question 1

A factory releases SO₂ at a rate of 200 g/s from a stack of height 75 meters. Calculate the expected concentration at a location 250 meters downwind under conditions classified as stability class B.

💡 Hint: Use the appropriate dispersion equations and consider how stability class influences σ.

Question 2

Imagine we have three pollution sources near a residential area emitting various rates of SO₂. If each stack has a different height and stability class, discuss how you would approach estimating combined emissions and pollutant concentrations.

💡 Hint: Think about how the contributions from each source interact.
