Challenge Problems

Push your limits with challenges.

Question 1

Assume a chemical has a higher volatility than water. A spill occurred; outline the potential environmental changes in concentration in both air and water over time.

💡 Hint: Utilize the mass transfer coefficient correlations for both phases.

Question 2

Given a lake with an initial concentration of A, describe how you would model its dilution over a certain period, considering both evaporation and potential inflow.

💡 Hint: Think about the effects of constant inflow on the overall concentration in the system.
