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.
