Challenge Problems
Push your limits with challenges.
Question 1
Calculate the shear stress in a fluid between plates with a dynamic viscosity of 0.05 Pa.s and a velocity gradient of 200 s⁻¹.
💡 Hint: Use the relation τ = μ * (du/dy) to solve.
Question 2
A liquid behaves like a Bingham plastic. If the yield stress is 5 Pa and the applied stress is 15 Pa, calculate the flow rate given its viscosity is 0.1 Pa.s.
💡 Hint: Don't forget to subtract the yield stress from applied stress before dividing.
