Question 1

What does Fick's Law state about the relationship between concentration and mass flux?

  • Mass flux increases with an increase in concentration
  • Mass flux decreases with an increase in concentration
  • Mass flux is independent of concentration

💡 Hint: Consider how substances move in response to concentration differences.

Question 2

True or False: Higher viscosity results in increased diffusion rates.

  • True
  • False

💡 Hint: Think about how thick liquids behave compared to lighter fluids.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the mass flux of a pollutant that has a concentration difference of 12 mg/L across a distance of 0.5 m, if the diffusion coefficient in the medium is 0.015 m²/s.

💡 Hint: Remember to pay attention to the units, ensuring consistency across the calculations.

Question 2

Describe how you would design an experiment to assess the impact of increased fluid velocity on the rate of mass transfer in a controlled environment, and what variables you would measure.

💡 Hint: Think about what tools you would need to accurately monitor and measure the affecting variables.
