Challenge Problems

Push your limits with challenges.

Question 1

You have five variables in a fluid system: velocity (V), pipe diameter (D), fluid density (ρ), dynamic viscosity (μ), and pressure drop (Δp). Apply the Buckingham Pi Theorem to form your dimensionless groups.

💡 Hint: Focus on finding the reference dimensions and reducing the variables.

Question 2

In an experiment, the pressure drop (Δp) across a pipe is observed versus the flow velocity (V) under controlled conditions. How can dimensional analysis expand your findings to other scenarios with different fluid properties?

💡 Hint: Think about how different dimensions interact and can be scaled.
