Challenge Problems
Push your limits with challenges.
Question 1
A fluid has a shear stress of 12 N/m² and a viscosity of 3 N·s/m². What is the velocity gradient?
💡 Hint: Use the relationship of shear stress and viscosity to find the gradient.
Question 2
Describe the implications for non-Newtonian fluids in engineering applications where fluid behavior varies with shear rate.
💡 Hint: Consider where different forces might apply.
