8.5. Applications of Fluid Mechanics

Try these first

1. 1.

   Define the Navier-Stokes equations.

   Hint

   Think about the conservation of mass and momentum.

2. 2.

   What is a Newtonian fluid?

   Hint

   Focus on how viscosity behaves in Newtonian fluids.

3. 3.

   What do Navier-Stokes equations describe?

   • Solid motion
   • Fluid motion
   • Gas motion

   Hint

   Identifying the common fluid behaviors can help.

4. 4.

   Is a Newtonian fluid characterized by changing viscosity?

   • True
   • False

   Hint

   Recall the definition of Newtonian fluid properties.

5. 5.

   Describe a scenario where fluid flow transitions between laminar and turbulent. Explain the impact on the fluid equations used.

   Hint

   Consider how Reynolds number factors into flow transitions.

6. 6.

   Given a problem where a fluid flows through two different mediums with varying viscosities, formulate the boundary conditions to be used.

   Hint

   Think about the properties of the fluids involved.
