Challenge Problems
Push your limits with advanced challenges
A barge spills DNAPL in a river with a concentration of 10 g/L in the sediment. If the water concentration must remain below 1 g/L to avoid ecological damage, calculate the allowable flux using a mass transfer coefficient of 0.5 cm/h.
💡 Hint: Be sure to clarify what V* and V represent in this context.
Discuss how different temperatures might affect the mass transfer coefficient when modeling a spill. Give examples of how real-world consequences might differ based on temperature changes.
💡 Hint: Consider how physical principles of fluid dynamics apply in your discussion.
