Show hintHide hint
Think about what happens to pressure at the start of flow.
Question 2.
What does Reynolds number indicate?
Show hintHide hint
Recall the contexts in which it is used.
3Question 3.
What characterizes fully developed laminar flow?
- Constant pressure drop
- Increasing pressure drop
