Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a fluid with a velocity of 4 m/s, characteristic length of 0.5 m, and kinematic viscosity of 0.002 m²/s, calculate the Reynolds number and discuss its implications for the flow type.

💡 Hint: Use the Reynolds number formula, and think about how it categorizes flow.

Challenge 2 Hard

In turbulent flow, if the energy dissipation rate drops, how would that affect flow behavior and Reynolds number?

💡 Hint: Consider the relationship between energy and turbulence.
