Challenge Problems
Push your limits with advanced challenges
You want to design an experiment on the drag force acting on a sphere in water and air. Define the parameters, outline the steps for dimensional analysis, and determine what dimensionless groups would be necessary.
💡 Hint: Think about how these variables relate to one another in fluid flow.
Given a scenario where a pipe diameter increases, resulting in turbulent flow, suggest a method for determining the new Reynolds number and anticipating changes in fluid behavior.
💡 Hint: What do you already know about how flow transitions from laminar to turbulent based on Reynolds number?
