Show hintHide hint
What does it relate to regarding area?
3Question 3.
What is the main factor contributing to head loss during sudden enlargement?
- Turbulence

- Temperature
Show hintHide hint
Consider fluid dynamics around abrupt changes.
4Question 4.
True or False: Gradual enlargement increases head loss compared to sudden enlargement.
- True
- False
Show hintHide hint
Think about how transitions are managed in smooth enlargements.
Question 5.
A pipe has a diameter of 20 cm and suddenly enlarges to 40 cm. If water flows at 3 m/s in the smaller pipe, calculate the head loss due to sudden enlargement.
Show hintHide hint
Focus on calculating the area ratio properly.
Question 6.
