Challenge Problems
Push your limits with challenges.
Question 1
Calculate the shear stress at the wall if the maximum velocity is 0.8 m/s and the viscosity is 0.01 Pa·s.
💡 Hint: Review the relationship between velocity and shear stress.
Question 2
In a laminar flow scenario, if the distance between plates is halved, what happens to the maximum velocity?
💡 Hint: Consider how the geometry affects flow and apply known equations.
