6. Fluid Mechanics

Try these first

1. 1.

   What is Cauchy's Equation used for in fluid mechanics?

   Hint

   Think about the basic principles of momentum.

2. 2.

   Define Computational Fluid Dynamics (CFD).

   Hint

   It involves computers and fluid dynamics.

3. 3.

   What does Cauchy's Equation represent?

   • Momentum balance
   • Energy conservation
   • Mass conservation

   Hint

   Remember the focus on motion and forces.

4. 4.

   True or False: Navier-Stokes equations are only applicable to ideal fluids.

   • True
   • False

   Hint

   Think about real-world fluid behavior.

5. 5.

   Explain how applying the Reynolds transport theorem changes the way we look at momentum flows in a control volume.

   Hint

   Think about momentum conservation and how it flows.

6. 6.

   Devise a problem where a differential change in fluid properties (density/velocity) leads to a notable modification in flow patterns using Cauchy’s or Navier-Stokes equations.

   Hint

   Consider how temperature could influence the density of fluid.
