5.1. Summary of Mass Transfer Principles

Try these first

1. 1.

   Define flux in the context of mass transfer.

   Hint

   Think about how many particles are moving through a specific area.

2. 2.

   What does Fick's law state?

   Hint

   Recall how particles behave between high and low concentrations.

3. 3.

   What does Fick's Law describe?

   • Pressure changes
   • Diffusion processes
   • Chemical reactions

   Hint

   What is the law focused on regarding particles?

4. 4.

   True or False: Higher viscosity in a medium increases mass transfer resistance.

   • True
   • False

   Hint

   Think about how syrup flows compared to water.

5. 5.

   Given a specific diffusion coefficient, calculate the time it would take for a pollutant to diffuse 2 meters through a medium. Assume steady state applies.

   Hint

   Identify how distance and diffusion coefficient interact.

6. 6.

   Compare the mass transfer rates of two solvents with differing molecular weights and densities. Analyze how the differences impact environmental outcomes.

   Hint

   Reflect on real-life scenarios where these conditions may apply.
