Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple fluid mechanics experiment to test the relation of drag force on different cylinder diameters while maintaining constant velocity and viscosity. What dimensionless groups would you utilize?

💡 Hint: Think of how different diameters can alter the flow characteristics and the importance of dimensionless groups.

Challenge 2 Hard

Using Buckingham's theorem, there are four variables: force (F), density (ρ), viscosity (μ), and velocity (V). Assuming these are the only dimensions, calculate the number of dimensionless groups.

💡 Hint: Remember to count the basic dimensions correctly and adjust for the number of variables.
