Challenge Problems

Push your limits with challenges.

Question 1

You are tasked to analyze the drag force experienced by a sphere in a flowing liquid. Using Buckingham's Pi theorem, identify the dimensionless parameters involved and outline your experimental approach.

💡 Hint: Consider the fundamental dimensions at play and how they influence the behavior of the fluid.

Question 2

Create a dimensional analysis for an equation describing the drag force acting on a flat plate submerged in a fluid. Discuss the impact of each variable on the drag force as per the analysis.

💡 Hint: Think about how your choice of area might change with different orientations or conditions.
