Challenge Problems
Push your limits with challenges.
Question 1
Given a turbulent flow in a pipe, calculate the shear stress if the velocity defect at a specific radius is 2 m/s and the fluid density is 800 kg/m³.
💡 Hint: Focus on deriving u* first using the velocity defect.
Question 2
If the height of surface irregularities is 0.1 mm and the viscous sublayer thickness is measured at 0.4 mm, classify the boundary as smooth, rough, or transitional.
💡 Hint: Refer to the classification criteria discussed in class.
