Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical pipe has a diameter of 0.1 m, and water flows through it at a velocity of 3 m/s. If the dynamic viscosity is known to be 0.001 Pa·s, calculate the Reynolds number. Discuss if the flow is laminar or turbulent.
💡 Hint: Use the formula and break down your calculations.
Question 2
Compare two scenarios: a thin oil flowing at low speed compared to water flowing rapidly through a pipe. Discuss how Reynolds number aids in predicting behavior in each case.
💡 Hint: Reflect on how viscosity and velocity interact.
