5.1.1. Fluid Flow Analysis

Try these first

1. 1.

   What is the difference between a system and a control volume?

   Hint

   Think about fixed mass vs. defined space.

2. 2.

   Can you name one flow analysis technique?

   Hint

   Consider the types of research methods used.

3. 3.

   What defines a system in fluid mechanics?

   • A fixed mass of fluid
   • An imaginary volume
   • A moving boundary

   Hint

   Focus on mass vs. space.

4. 4.

   True or False: Control volumes are useful in understanding flow interactions.

   • True
   • False

   Hint

   Think about how we define exchange in areas.

5. 5.

   Calculate the drag force acting on a cylinder in a wind tunnel, given its diameter, wind speed, and fluid density. Assume standard conditions.

   Hint

   Identify the parameters needed from the problem statement.

6. 6.

   Analyze the stability of a civil structure exposed to high wind speeds. Identify which analysis techniques would be most useful.

   Hint

   Consider practical measurement contrasting with theoretical modeling.
