7. Fluid Mechanics

Try these first

1. 1.

   Define the Navier-Stokes equations.

   Hint

   Think about how fluids behave under motion.

2. 2.

   What is the difference between a Newtonian and a non-Newtonian fluid?

   Hint

   Consider how each type of fluid responds to applied force.

3. 3.

   Who are the researchers behind the Navier-Stokes equations?

   • Newton and Stokes
   • Navier and Stokes
   • Cauchy and Newton

   Hint

   Remember both names when recalling their contributions.

4. 4.

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

   • True
   • False

   Hint

   Think about how different fluids behave under stress.

5. 5.

   Given a fluid flow through a pipe with varying diameter, explain how the Navier-Stokes equations can be applied to predict pressure changes.

   Hint

   Consider how diameter changes affect velocity and pressure.

6. 6.

   Explain the challenges in solving the Navier-Stokes equations for turbulent flow.

   Hint

   Think about how chaos complicates predictability in fluid motion.
