7.3.1. Application of Newton's Laws

Try these first

1. 1.

   What is Newton's second law?

   Hint

   Think of the relationship between force and motion.

2. 2.

   Define incompressible flow.

   Hint

   Remember the term 'constant density'!

3. 3.

   What does the Navier-Stokes equation help to model?

   • Solid motion
   • Fluid motion
   • Static forces

   Hint

   Focus on what types of substances these equations apply to.

4. 4.

   True or False: Non-Newtonian fluids always maintain a constant viscosity.

   • True
   • False

   Hint

   Think of examples like ketchup or whipped cream.

5. 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?

   Hint

   Consider conservation of mass and how diameter affects speed.

6. 6.

   Discuss how changing temperature in a fluid can alter its flow characteristics and its classification as Newtonian or non-Newtonian.

   Hint

   Relate temperature changes to viscosity and fluid behavior review.
