Challenge Problems
Push your limits with challenges.
Question 1
A hockey puck is gliding over a surface of ice. If the ice is 0.1 m thick and has a viscosity of 0.001 Pa.s, what’s the force due to viscosity?
💡 Hint: You might need to consider the velocity gradient to proceed.
Question 2
A fluid layer of thickness 0.5 mm flows between two plates. If the dynamic viscosity is 5 Pa.s and the velocity of the top plate is 0.1 m/s, find the shear force acting on the surface.
💡 Hint: Identify your surface area and work through the calculations.
