A:
- Name four physical quantities that are conserved and two quantities that are not conserved
during a process.
- Define mass and volume flow rates. How are they related to each other?
- Does the amount of mass entering a control volume have to be equal to the amount of mass
leaving during an unsteady flow process?
- When is the flow through a control volume steady?
- Consider a device with one inlet and one outlet. If the volume flow rates at the inlet and at
the outlet are the same, is the flow through this device necessarily steady? Why?
