Challenge Problems
Push your limits with challenges.
Question 1
A flow in a pipe shows laminar behavior with a Reynolds number of 500. If the velocity increases causing the Reynolds number to rise to 3000, what type of flow is expected, and what factors might lead to turbulence?
💡 Hint: Relate flow characteristics to Reynolds number values.
Question 2
Evaluate a scenario where water flows over a spillway. Given the Froude number is 1.2, what does this indicate about the flow regime?
💡 Hint: Associate low and high Froude numbers with energy and flow behavior.
