Challenge Problems
Push your limits with advanced challenges
A pollution plume is detected in a river undergoing a flood. Compare the rate of transport due to bulk flow versus diffusion in this scenario. How would you model this transportation?
💡 Hint: Consider the equations used in fluid dynamics.
Design an experiment to measure the diffusion rate of a dye in both still water and flowing water. What variables will you control and measure?
💡 Hint: Think about the impact of flow on diffusion distance over a set time.
