6.1.4. Cavitation

Try these first

1. 1.

   What is cavitation?

   Hint

   Think about what happens when pressure decreases in a fluid.

2. 2.

   What does a velocity field represent?

   Hint

   Consider how fluid movement can vary in different spaces.

3. 3.

   What is cavitation?

   • A solid forming in liquid
   • Vapor bubble formation due to low pressure
   • The increase of fluid velocity

   Hint

   Think about the conditions under which bubbles can form.

4. 4.

   True or False: A pressure gradient can affect fluid velocity.

   • True
   • False

   Hint

   Consider how fluids naturally flow towards lower pressure.

5. 5.

   Given a fluid system, perform calculations to determine pressure conditions under which cavitation may begin. Include a discussion on the relevant properties of the fluid.

   Hint

   Think about how pressure and temperature relate to vapor bubbles.

6. 6.

   Analyze a real-world example of a fluid system affected by cavitation, outlining the physical principles at play, and propose engineering solutions to mitigate these effects.

   Hint

   Consider how design changes can alter flow and pressure.
