Question 1.
Define isentropic flow.
Show hintHide hint
Think about processes with no heat transfer.
Question 2.
What is choked flow?
Show hintHide hint
Consider where maximum flow is attained.
3Question 3.
What defines isentropic flow?
- A process with heat exchange

- Only involves liquids
Show hintHide hint
Consider the definition and what 'isentropic' implies.
4Question 4.
True or False: Choked flow occurs at Mach number < 1.
- True
- False
Show hintHide hint
Think about the conditions in a nozzle.
Question 5.
