5.5. Summary and Applications

Try these first

1. 1.

   Define a system in fluid mechanics.

   Hint

   Think about what we consider when studying fluids.

2. 2.

   What is a control volume?

   Hint

   It's related to the boundaries around a flow region.

3. 3.

   What differentiates a system from a control volume in fluid mechanics?

   • A system has fixed mass
   • whereas control volume is a defined space for fluid flow.
   • A system is always larger than a control volume.
   • Control volume describes a particle
   • whereas a system describes a region.

   Hint

   Think about which one allows fluid to flow freely.

4. 4.

   True or False: Experimental methods do not contribute to analytical flow studies.

   • True
   • False

   Hint

   Consider the relationship between empirical data and theoretical analysis.

5. 5.

   Describe a method to analyze the fluid flow over a complex geometry structure, such as a racing car, using both experimental and computational fluid dynamics approaches.

   Hint

   Think about testing designs and refining them using empirical data.

6. 6.

   Explain how changes in boundary conditions might affect the lift and drag forces on the previously discussed bird example.

   Hint

   Consider how different wind conditions change the flight dynamics.
