Challenge Problems

Push your limits with challenges.

Question 1

Given a turbulent flow scenario with a pipe diameter of 0.1 m, maximum velocity of 4 m/s at the center, and density of 1000 kg/m³, calculate the shear stress at the wall.

💡 Hint: Consider the relationships between flow characteristics and utilize derived equations.

Question 2

Analyze the impact of surface roughness on shear stress in a transition from smooth to rough boundaries, focusing particularly on practical implications for fluid transport systems.

💡 Hint: Use experimental results such as Nikuradse's findings for deeper insights.
