Question 1.
What is a system in fluid mechanics?
Show hintHide hint
Think about the fixed quantity of matter.
Question 2.
Define a control volume.
Show hintHide hint
Consider how we often observe fluid interactions.
3Question 3.
What is the main distinction between a system and a control volume?
- A system includes boundary conditions.
- A system is a fixed mass
- while a control volume captures flow changes.
- A control volume is fixed while a system varies.
Show hintHide hint
Focus on the fixed versus changing nature of analysis.
4Question 4.
True or false: State relationships do not affect flow analysis in control volumes.
- True
- False
Show hintHide hint
Consider the role of pressure and temperature in behavior.
Question 5.
Design an experiment using a control volume approach to analyze airflow over a bridge, detailing your methods.
Show hintHide hint
Think about how you would measure forces impacting the structure.
Question 6.
How can you improve the accuracy of analytical flow model predictions for a river's flow?
Show hintHide hint
Consider factors outside simple constants, such as bottom topography.
