Recall what the title emphasizes.
4Question 4.
True or False: In a fixed control volume, the control boundaries remain stationary.
- True
- False
Show hintHide hint
Think about the word 'fixed'.
Question 5.
A tank is filled with water. Water enters at 5 L/min and exits at 2 L/min. What is the rate of change of water in the tank?
Show hintHide hint
Think of inflow and outflow rates.
Question 6.
Consider a pipe with a varying diameter that causes the velocity of water to increase. Describe how this relates to mass conservation.
Show hintHide hint
Remember the continuity equation is also tied to mass conservation.
