Question 1

What is the main assumption of the steady-state model?

  • Concentration changes over time
  • Concentration remains constant over time
  • Emission rates fluctuate

💡 Hint: Think about what steady means in terms of measurements.

Question 2

True or False: Higher emission sources lead to lower peak concentrations.

  • True
  • False

💡 Hint: Consider how height affects the spread of pollutants.

Challenge Problems

Push your limits with challenges.

Question 1

If an emission source expels pollutants at a rate of Q = 100 kg/s, and is situated at a height of 20 meters, how does this affect the distribution of pollutants? Calculate concentration if spread is defined by C3_y = 5m and C3_z = 3m.

💡 Hint: Start by understanding how to apply Gaussian dispersion equations with the given variables.

Question 2

A factory emits pollutants from 15 meters high, with Q = 200 kg/s. Discuss how seasonal wind variation could influence the dispersion model and the expected change in peak concentration.

💡 Hint: Think about how wind shifts could reshape pollution impacts through their influence on dispersal paths.
