Challenge Problems
Push your limits with challenges.
Question 1
In a specific scenario, you need to model the mass transfer of a pollutant in a river. Given the flow velocity and concentration gradients at various points, predict how changes in the boundary layer thickness would affect the pollutant dispersion.
💡 Hint: Think about how several factors, including flow speed and obstacles, could alter the layer.
Question 2
Design a heat exchanger based on the mass transfer principles discussed. Consider how to minimize resistance in boundary layers during operation.
💡 Hint: Look for ways that promote turbulence.
