2 cards from this section. Quick, good the night before a test.
What does the mass transfer coefficient indicate?
Think about what flows between phases.
Name one factor that affects the mass transfer coefficient.
Refer to the acronym you learned - FLOW.
What is the overall mass transfer coefficient?
It relates to how substances exchange across surfaces.
True or False: The resistance model indicates total resistance is just the resistance of the gas phase.
Think of a layered cake model.
Calculate the mass transfer flux given a known mass transfer coefficient of 0.005 m/s, a water concentration of 0.1 mol/m³, and air saturation concentration of 0.02 mol/m³.
Remember to follow the relationship involving coefficients and concentrations.
Describe how changing temperature affects mass transfer coefficients in gaseous systems.
Think about how heating liquids changes their flow and transfer.
