2. 2.

   What does a velocity field represent?

   Hint

   Consider the components of velocity in three dimensions.

3. 3.

   What is the primary purpose of using analytical solutions in fluid dynamics?

   • To visualize flow patterns
   • To provide precise mathematical relationships
   • To predict future weather

   Hint

   Think about what analytical solutions aim to achieve.

4. 4.

   True or False: Streamlines, pathlines, and streaklines are all the same for unsteady flows.

   • True
   • False

   Hint

   Consider how time affects these flow lines.

5. 5.

   An engineer is tasked with designing a piping system for a chemical process. What methods would they employ to ensure effective fluid flow, and how would analytical and computational techniques assist in this endeavor?

   Hint

   Consider how combining different methods can lead to better design outcomes.

6. 6.

   An experiment shows that as fluid velocity increases, a certain section of the flow experiences cavitation. Explain the underlying physics using concepts discussed in this section.

   Hint

   Relate velocity changes to pressure variations comprehensively to explain the phenomenon.
