Challenge Problems
Push your limits with advanced challenges
A pollutant source emits gases at 10 meters height. If the surrounding atmospheric lapse rate is -0.006 °C/m, calculate the mixing height and discuss the implications for dispersion.
💡 Hint: Recall how the mixing height is defined when lapse rates intersect.
Discuss how changing environmental conditions (temperature inversion) might alter expected plume behavior for a factory emitting pollutants on a warm day.
💡 Hint: Visualize the inversions as a lid restricting upward air movement.
