Challenge Problems
Push your limits with challenges.
Question 1
Given a lake where the inflow of pollutants is 10 g/day and the evaporation rate is 3 g/day. Develop the mass balance equation for the lake and calculate the concentration after one day assuming the lake has a volume of 1000 L.
💡 Hint: Use the mass outflow and inflow rates to determine the change in concentration.
Question 2
Discuss the real-world application of box models in a specific river system, noting any simplifications that may be required.
💡 Hint: Consider how segmentation might ignore localized events but simplify overall modeling.
