Challenge Problems
Push your limits with advanced challenges
Discuss what happens to flow assumptions in a scenario where a fluid is heated rapidly. How does this challenge the assumptions of incompressibility and isothermal conditions?
💡 Hint: Consider the implications of thermal expansion and variations.
Provide a case study of fluid flow over a heat exchanger, highlighting how the assumptions of incompressibility and isothermal conditions can be challenged.
💡 Hint: Evaluate scenarios of highly variable temperatures or fluid composition.
