Challenge Problems
Push your limits with challenges.
Question 1
Calculate the flux if the concentration of a pollutant at height 1 is 600 µg/m³ and at height 2 is 400 µg/m³ over 10 meters with a diffusion coefficient of 2 m²/s.
💡 Hint: Use the gradient formula to solve.
Question 2
Explain how non-instantaneous concentration measurements could lead to errors in estimating flux.
💡 Hint: Reflect on temporal changes in pollutant levels.
