Challenge Problems
Push your limits with challenges.
Question 1
In a river contaminated with a pollutant, using the box model, how would you determine the effectiveness of bioremediation efforts over time based on mass transfer?
💡 Hint: Focus on changes in concentration levels and rates over designated time frames.
Question 2
Analyze a scenario where a change in flow velocity impacts pollutant spread. How might you theoretically describe this using mass transfer equations?
💡 Hint: Consider how higher velocities impact diffusion layers at interfaces!
