Challenge Problems
Push your limits with challenges.
Question 1
A lake has a steady rate of pollution entry at 5 kg/day and loses 2 kg/day through evaporation. What will be the concentration change given a volume of 1000 m³?
💡 Hint: Consider both generation and loss to calculate net rates.
Question 2
Discuss how incorporating tributaries with different pollutant concentrations affects the mass balance of a river. How would you adjust your equations?
💡 Hint: Think of each tributary as an additional input into the mass balance.
