Challenge Problems
Push your limits with challenges.
Question 1
A fluid between parallel plates experiences a velocity gradient of 5 m/s over a distance of 0.1 m. Calculate the shear stress if the viscosity of the fluid is 0.8 Pa.s.
💡 Hint: Make sure to use the right units for viscosity and gradient!
Question 2
Explain the difference in viscosity behavior when temperature is increased for water (liquid) and air (gas).
💡 Hint: Think about how heat influences both types of fluids distinctly.
