Question 1.
What is Newton's second law?
Show hintHide hint
Think of the relationship between force and motion.
Question 2.
Define incompressible flow.
Show hintHide hint
Remember the term 'constant density'!
3Question 3.
What does the Navier-Stokes equation help to model?
- Solid motion
- Fluid motion
- Static forces
Show hintHide hint
Focus on what types of substances these equations apply to.
4Question 4.
True or False: Non-Newtonian fluids always maintain a constant viscosity.
- True
- False
Show hintHide hint
Think of examples like ketchup or whipped cream.
Question 5.
A fluid is flowing through a pipe with varying diameter and pressure. How would you use the Navier-Stokes equations to analyze this situation?
Show hintHide hint
Consider conservation of mass and how diameter affects speed.
Question 6.
Discuss how changing temperature in a fluid can alter its flow characteristics and its classification as Newtonian or non-Newtonian.
Show hintHide hint
Relate temperature changes to viscosity and fluid behavior review.
