Question 1

Which of the following is a characteristic of Newtonian fluids?

  • They have a variable viscosity
  • They maintain a constant viscosity under shear.
  • They require a specific yield stress to flow.

💡 Hint: Recall the definition of Newtonian fluids.

Question 2

True or False: Shear-thinning fluids increase in viscosity with increased shear rate.

  • True
  • False

💡 Hint: Consider how a thick liquid might behave when it is agitated.

Challenge Problems

Push your limits with challenges.

Question 1

Given a fluid that behaves as a shear-thinning fluid in a pipeline, describe how the viscosity might change if flow rates increase significantly over time. What real-world scenarios might illustrate this effect?

💡 Hint: Think about how different types of liquids are handled on assembly lines.

Question 2

In an application where a Bingham plastic is used, explain how the applied stress influences its flow under varying conditions, and suggest potential issues that might arise in mechanical systems.

💡 Hint: Consider how different forces affect system efficiency.
