Show hintHide hint
Think about how they behave in space.
Question 2.
What does the Reynolds transport theorem relate?
Show hintHide hint
Consider mass and energy balance.
3Question 3.
What is the Reynolds transport theorem used for?
- To calculate pressure
- To relate system dynamics to control volume
