3 cards from this section. Quick, good the night before a test.
Define mass transfer coefficient.
Consider it as a speed indicator for solute movement.
What does flux measure in mass transfer?
Think of it like flow rate but specifically for mass.
What does the mass transfer coefficient represent?
Think of it as a speed for moving things.
True or False: Resistance in series means you can sum up resistances to find overall resistance.
Recall how components share flow in circuits.
A polluted lake is monitored for chemical flux. The measured concentrations are as follows: Bulk liquid concentration is 20 mg/L, and gas concentration is 0.02 mg/L. Using an estimated mass transfer coefficient of 0.5, calculate the expected mass transfer flux.
Ensure you account for units when calculating flux.
In a lab experiment, a gas phase has a resistance of 10 and a liquid phase resistance of 5. If the overall mass transfer rate needed is 2, determine if adjustments are needed and what strategy could enhance transfer.
Consider the role of modifying temperature or flow patterns in the system.
