Question 1.
Define control volume in your own words.
Show hintHide hint
Think about a specific area in which fluid flow is analyzed.
Question 2.
What does steady flow mean?
Show hintHide hint
Consider if the flow conditions are changing or constant.
3Question 3.
What does the mass conservation principle state?
- Mass inflow equals mass outflow.
- Mass inflow exceeds mass outflow.
- Mass outflow is zero.
Show hintHide hint
Consider how mass behaves in a closed system.
4Question 4.
True or False: Steady flow indicates that conditions are changing over time.
- True
- False
Show hintHide hint
Focus on the implications of 'steady' as constant.
Question 5.
A reservoir supplies water to two pipes simultaneously. If Pipe A has a flow of 10 L/s and Pipe B has a flow of 15 L/s, what is the total mass conservation in the system?
Show hintHide hint
Think about the inflow and outflow relationship.
Question 6.
Analyze a scenario where the inflow is constant but the outflow fluctuates. How would you manage the control volume to maintain mass conservation?
Show hintHide hint
Recall control volume management principles.
