Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe diameter of 0.1m and a center velocity of 5 m/s, calculate the wall shear stress if the water density is 1000 kg/m³.
💡 Hint: Remember, u* relates to maximum velocity and the velocity gradient near the wall.
Question 2
A pipeline has an average height of irregularities of 0.3mm. Given the thickness of the viscous sublayer is 0.6mm, categorize the boundary.
💡 Hint: Use the ratios we discussed on boundaries to evaluate.
