Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows through a long, smooth pipe at a velocity of 1 m/s. If the diameter of the pipe is doubled, how does the Reynolds number change assuming viscosity stays the same?
💡 Hint: Remember the Reynolds number formula: Re = (density × velocity × diameter) / viscosity.
Question 2
Design an experiment to demonstrate the transition from laminar to turbulent flow using water and a dye. Describe the setup and the expected observations.
💡 Hint: Focus on the visualization aspects with dye to observe the patterns.
