9. Fluid Mechanics

Try these first

1. 1.

   Define vorticity in your own words.

   Hint

   Think about how rotation is measured.

2. 2.

   What is the main function of Particle Image Velocimetry?

   Hint

   Consider its role in capturing fluid movement.

3. 3.

   What is the main purpose of vorticity in fluid kinematics?

   • A. To measure pressure
   • B. To measure rotation
   • C. To measure density

   Hint

   Consider the concept of rotation.

4. 4.

   True or False: The Eulerian perspective tracks individual fluid particles.

   • True
   • False

   Hint

   Think about how each perspective operates.

5. 5.

   Given a fluid moving with a vorticity of 0.5 s^-1, calculate the angular velocity of a fluid particle.

   Hint

   Double the vorticity value to find angular velocity.

6. 6.

   Describe how you would set up an experiment to measure turbulent flow using PIV.

   Hint

   Consider the equipment needed for both illumination and observation.
