Challenge Problems
Push your limits with advanced challenges
Consider a small control volume in a flowing fluid. How would you approach deriving Cauchy's equation, and what assumptions will you base this on?
💡 Hint: Relate each step back to the assumptions discussed.
Discuss how transitions from laminar to turbulent flows challenge the assumptions made in fluid mechanics.
💡 Hint: Think about how fluid properties change with different flow regimes.
