Push your limits with advanced challenges
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.
💡 Hint: 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.
💡 Hint: Consider the role of modifying temperature or flow patterns in the system.
