Question 1.
What does the mass transfer coefficient (K) measure?
Show hintHide hint
Think about transferring something between two different materials.
Question 2.
Give an example of a dense non-aqueous phase liquid.
Show hintHide hint
What kind of chemical is known to sink in water?
3Question 3.
What is the role of the mass transfer coefficient?
- A measure of density
- Rate of substance transfer
- Environmental clean-up cost
Show hintHide hint
Think about what it measures in substance interactions.
4Question 4.
True or False: DNAPL floats on water.
- True
- False
Show hintHide hint
Consider the definition of DNAPL.
Question 5.
Given a scenario where a DNAPL is introduced into a flowing river, analyze the expected impact on local sediment and water concentration over time using mass transfer principles.
Show hintHide hint
Consider variables like flow speed and the K coefficients you have discussed.
Question 6.
Design an experiment to measure the mass transfer coefficients for a new chemical pollutant in a controlled water tank, detailing each step and expected outcomes.
Show hintHide hint
Remember to ensure you are documenting relevant conditions to apply the right empirical correlations.
