2.4. Assumptions in Mass Transfer

Try these first

1. 1.

   What is mass transfer resistance?

   Hint

   Think about barriers that slow down movement.

2. 2.

   Define steady state in mass transfer.

   Hint

   Consider what happens over time in a flowing system.

3. 3.

   What assumption allows us to simplify mass transfer calculations at interfaces?

   • Dynamic state
   • Steady state
   • Accumulated state

   Hint

   Consider the opposite of transient conditions.

4. 4.

   True or False: Mass transfer resistance is influenced solely by concentration differences.

   • True
   • False

   Hint

   Think about different phases’ characteristics.

5. 5.

   Evaluate how temperature changes affect mass transfer resistance at the air-water interface.

   Hint

   Think about how heat influences molecular interactions.

6. 6.

   Given a scenario where two liquids with differing densities are mixed, analyze how this affects mass transfer resistance at their interface.

   Hint
