Show hintHide hint
Think about the volume you measure for fluid properties.
Question 2.
What is the principle of mass conservation?
Show hintHide hint
Consider the law of conservation.
3Question 3.
What is a control volume?
- A closed container
- A defined region in space for analysis

- True
- False
Show hintHide hint
Consider the law of conservation.
Question 5.
A cylindrical tank has an inflow of water at 10 m³/h and an outflow at 7 m³/h. How much mass is accumulated in the tank after 2 hours?
Show hintHide hint
Think about how to incorporate inflow and outflow over time.
Question 6.
