Question 1.
What is a control volume?
Show hintHide hint
Think of it as a specific area in fluid dynamics.
Question 2.
What does the principle of mass conservation state?
Show hintHide hint
Focus on the idea of mass balance.
3Question 3.
What principle does the mass conservation equation represent?
- Mass can be created
- Mass is constant
- Mass is variable
Show hintHide hint
Think about how mass behaves in fluid dynamics.
4Question 4.
The divergence of velocity vectors indicates the presence of what?
- True
- False
Show hintHide hint
Recall the physical interpretations of divergence.
Question 5.
Consider a cylindrical tank filled with water. If the inflow rate is 10 L/min and the outflow rate is 8 L/min, what is the net change in mass within the tank over 10 minutes?
Show hintHide hint
Calculate the difference between inflow and outflow rates first.
Question 6.
