1. 1.

   Define vorticity in fluid mechanics.

   Hint

   Think about rotation in fluids.

2. 2.

   What does Particle Image Velocimetry (PIV) measure?

   Hint

   Consider methods of visualizing fluid flow.

3. 3.

   What does vorticity measure in fluid dynamics?

   • Fluid pressure
   • Fluid rotation
   • Fluid density

   Hint

   Consider fluid motion spiraling.

4. 4.
