What is the primary characteristic of turbulent flow?
💡 Hint: Think of how turbulent flow appears in nature like in rivers.
True or False: Shear stress decreases as you move away from the wall in turbulent flow.
💡 Hint: Consider the forces acting near the surface compared to deeper in the flow.

Challenge Problems
Push your limits with advanced challenges
A pipe with a diameter of 50 mm has a maximum velocity of 2 m/s at the center. If the shear stress at the wall is 70 Pa, calculate the velocity defect using the velocity defect law.
💡 Hint: Use appropriate units and remember the layers in turbulent flow can influence the answer.
Given water flowing through a rough pipe with an average height of irregularities of 0.3 mm and a kinematic viscosity of 0.01 m^2/s, determine if the flow is smooth, transitional, or rough.
💡 Hint: Reread the definitions and ensure to convert all measurements to consistent units.
