Challenge Problems

Push your limits with challenges.

Question 1

You want to analyze the flow in a large pipe with varying diameters, densities, and velocities. Explain how you would reduce the complexity of variables using dimensional analysis, including the steps involved in applying the Buckingham Pi theorem.

💡 Hint: Break down the process: which variables matter and how can you test them efficiently?

Question 2

Consider a scenario with fluid flowing through different channel shapes. How would you set up your experiments to validate the applicability of your findings by using dimensional groups?

💡 Hint: What shapes can help highlight the changes as variables?
