Challenge Problems
Push your limits with challenges.
Question 1
You have a container with air over a water surface. If an oil slick surfaces and spreads, how does this affect the mass transfer resistance in terms of both convection and diffusion?
💡 Hint: Consider how each layer (air, oil, water) interacts.
Question 2
In an experiment, increasing the flow velocity of water increases the mass transfer coefficient while also increasing the boundary layer thickness. Explain this contradictory situation.
💡 Hint: Think about how flows interact and create layers.
