6.2. Other Fluid Properties

Try these first

1. 1.

   What is a velocity field?

   Hint

   Think about how you'd express the speed of water in different locations.

2. 2.

   What does pressure gradient indicate?

   Hint

   Consider how air moves from high to low pressure.

3. 3.

   What is a velocity field?

   • A map of a city
   • Representation of fluid velocities
   • A static pressure system

   Hint

   Think about how water flows through a river in different areas.

4. 4.

   True or False: Cavitation only occurs in high-pressure systems.

   • True
   • False

   Hint

   Consider scenarios where the fluid might attempt to vaporize.

5. 5.

   You observe cavitation occurring in a pump system. What steps can you take to mitigate this issue?

   Hint

   Think about how adjusting the conditions of flow might change pressure.

6. 6.

   A jet is operating at a Mach number of 0.4. Explain how its behavior differs from a Mach number of 0.2 regarding density considerations.

   Hint

   Consider effects of high speeds on air compared to low speeds.
