Challenge Problems
Push your limits with challenges.
Question 1
A fluid with a viscosity of 0.9 Pa.s is coaxed between two plates 0.1 m apart. If the top plate moves at 2 m/s, find the shear stress.
💡 Hint: Remember to rearrange and apply appropriate units.
Question 2
During an experiment, a fluid at 20°C has a dynamic viscosity of 1.2 Pa.s. How much force is required to move a plate of area 0.5 m² at a velocity of 3 m/s if t = 0.05m?
💡 Hint: Make sure to calculate each component step by step.
