What does mass balance involve in pollution modeling?
💡 Hint: Think of it as a balance scale.

Challenge Problems
Push your limits with advanced challenges
A factory releases a pollutant at a constant rate. Over time, how would you expect the concentration at a monitoring station to behave? Discuss conditions that would validate your steady state assumptions.
💡 Hint: Reflect on what changes can influence pollutant transport.
Given a pollutant's rate of flow, derive how the concentration will behave if the emissions suddenly increase by 50%. What does this imply about steady state?
💡 Hint: Consider what happens to balance when sources increase suddenly.
