Challenge Problems
Push your limits with advanced challenges
You are tasked with designing an experiment to analyze the drag force on a sphere in two different fluids: oil and water. How would you go about selecting your variables and constructing dimensionless groups for this experiment?
💡 Hint: Recall the relevant variables and how to apply Buckingham's theorem to simplify your experimental design.
Describe the process of using dimensional analysis to estimate the time it takes for a viscous fluid to flow through a pipe of known diameter and length. What dimensionless groups might be useful here?
💡 Hint: Consider how different fluid characteristics interact with the geometric properties of the pipe.
