Challenge Problems
Push your limits with advanced challenges
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.
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.
