Challenge Problems
Push your limits with advanced challenges
Consider a case where water waves are propagating on a lake surface. If we assume irrotational flow, how would energy dissipation differ in real versus ideal fluids?
💡 Hint: Think about where energy goes in real flows and compare with ideal assumptions.
You’ve modeled a situation neglecting surface tension in a fluid. What scenarios could this lead to erroneous predictions, and how could you address this issue?
💡 Hint: Focus on environments where surface tension could be critically influencing.
