Challenge Problems
Push your limits with advanced challenges
Calculate the concentration of a pollutant at a distance of 500m from a source with an emission factor of 200 kg/hour and dispersion coefficients of σy = 10m and σz = 5m.
💡 Hint: Use the Gaussian formula to plug in values for q, σy, and σz.
Discuss how you would approach modeling the dispersion of pollutants in a stable atmosphere as opposed to an unstable one.
💡 Hint: Focus on how atmosphere stability impacts mixing and dispersion.
