Challenge Problems
Push your limits with advanced challenges
Given a Gaussian model with an emission rate of 100 kg/day and standard deviations of σy = 10 meters and σz = 5 meters, calculate the concentration at a point (20m, 10m, 0m).
💡 Hint: Use the Gaussian equation as a reference.
Describe what modifications to the Gaussian model would be necessary if the source of emissions changes height over time.
💡 Hint: Consider how changing elevation affects pollutant spread.
