Question 1.
What occurs to fluid velocity when it flows from a wider pipe to a narrower pipe?
Show hintHide hint
Consider the impact of cross-sectional area on flow.
Question 2.
Define vortex formation in fluid flow.
Show hintHide hint
Think about how fluid behaves in a circular path.
3Question 3.
What happens to fluid speed in a contraction?
- Increases
- Decreases
- Stays the same
Show hintHide hint
Think about fluid movement in relation to cross-sectional area.
4Question 4.
True or False: Energy loss is greater in expansions than in contractions.
- True
- False
Show hintHide hint
Visualize the flow patterns during expansion and contraction.
Question 5.
Design a water distribution system for a given community. Include considerations for flow contractions and expansions. Explain your design choices.
Show hintHide hint
Think about how pressure and flow characteristics change in different parts of the system.
Question 6.
Evaluate an existing piping system where high energy loss is reported. Suggest at least two modifications to improve efficiency.
Show hintHide hint
Consider where vortices are likely to form and how to smooth out those transitions.
