Challenge Problems

Push your limits with challenges.

Question 1

You have to analyze a flume flow characterized by a depth (D), discharge (Q), and slope (S). Using the Buckingham Pi theorem, describe the steps to find dimensionless groups.

💡 Hint: Start with variable listing and work through each step methodically.

Question 2

Propose an experiment to determine the impact of different fluid viscosities on pressure drop in a pipe. Describe how dimensional analysis would support your methodology.

💡 Hint: Focus on consistent variables and how they align with dimensionless analysis.
