5.4. Flow Analysis Techniques

Try these first

1. 1.

   What is a control volume?

   Hint

   Think about how we define a space for studying fluid flow.

2. 2.

   List two key fluid flow parameters.

   Hint

   Consider what describes how fluid flows.

3. 3.

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

   • A system is fixed; a control volume is not.
   • A control volume is always larger than a system.
   • Both are identical concepts.

   Hint

   Think about how each concept focuses on fluid flow.

4. 4.

   True or False: Velocity fields represent the distribution of fluid density during flow.

   • True
   • False

   Hint

   Consider what each type of field represents.

5. 5.

   Design a wind tunnel experiment to test how different shapes affect drag and lift on an object. Discuss the process and expected outcomes.

   Hint

   Consider how you would scale down real objects for your experiments.

6. 6.

   Given a scenario where wind speed increases and affects a tall building, derive the resulting pressure distributions around the structure using conservation principles.

   Hint

   What principles govern the behavior of wind acting on structures?
