Challenge Problems
Push your limits with advanced challenges
Design a comprehensive experiment to measure the pressure variation across different fluid densities and flow rates. Discuss the use of dimensionless parameters in reducing your experimental workload.
💡 Hint: Consider how different densities affect pressure and why that matters in design.
Given a scenario where a sphere is moving through a viscous fluid, calculate the drag force acting on it and how changing viscosity would affect this force. Use dimensionless analysis to support your conclusions.
💡 Hint: Think about how increasing viscosity would change flow patterns around the sphere.
