Question 1.
What does 'flux' refer to in environmental science?
Show hintHide hint
Think about how substances move between different sections in a box model.
Question 2.
Define DNAPL.
Show hintHide hint
Consider the properties of substances relative to water.
3Question 3.
What does DNAPL stand for?
- Dense Nitrile Phase Liquid
- Dense Non-Aqueous Phase Liquid
- Dilute Non-Aqueous Phase Liquid
Show hintHide hint
Focus on the density characteristic of the fluid.
4Question 4.
Are mass transfer coefficients constant across different environments?
- True
- False
Show hintHide hint
Consider the variables involved in different scenarios.
Question 5.
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.
Show hintHide hint
Be sure to clarify what V* and V represent in this context.
Question 6.
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.
Show hintHide hint
Consider how physical principles of fluid dynamics apply in your discussion.
