Challenge Problems
Push your limits with advanced challenges
You have a model of a pipe flow where the Reynolds number is maintained at 1500. Discuss the expected flow characteristics in both the model and its prototype.
💡 Hint: Consider how the Reynolds number informs your understanding of flow regimes.
Given a set of variables for a fluid flow experiment, outline how you would use the Buckingham Pi theorem to derive the necessary dimensionless groups.
💡 Hint: Think about which variables would serve as repeating variables in creating the groups.
