Try these first

1. 1.

   What is a velocity field?

   Hint

   Think of it like a map of flow speed.

2. 2.

   What does the pressure gradient indicate?

   Hint

   Remember, fluids move from high to low pressure.

3. 3.

   What component is not necessary in incompressible flow (Mach number < 0.3)?

   • Velocity Field
   • Pressure Field
   • Density Field

   Hint

   Focus on the conditions of flow.

4. 4.

   True or False: Streamlines, pathlines, and streaklines are different in unsteady flow.

   • True
   • False

   Hint

   Remember the definitions of each line.

5. 5.

   If given a cylindrical object and fluid flows around it at various velocities, how would you predict the pressure changes along the surface?

   Hint

   Account for how fluid speed affects pressure based on Bernoulli's principle.

6. 6.

   Design an experiment to measure the effects of cavitation in a hydraulic pump system. What parameters would you monitor?

   Hint

   Consider how you would replicate real operating conditions.
