Question 1.
Define minor losses in fluid flow.
Show hintHide hint
Think about what happens when fluid flows through fittings.
Question 2.
What does k_l represent in calculations?
Show hintHide hint
Recall how it is used in the formula for head loss.
3Question 3.
What is a minor loss in fluid systems?
- A loss due to friction over long distances
- A loss due to changes in velocity or direction
- A loss due to temperature variations
Show hintHide hint
Consider where in a system the changes might occur most frequently.
4Question 4.
True or False: Minor losses are always negligible compared to major losses in all systems.
- True
- False
Show hintHide hint
Think about pipe lengths and fittings.
Question 5.
A fluid flows through a pipe with an expansion from 50 mm to 100 mm diameter. The speed at the smaller diameter is 2 m/s. Calculate the k_l for this expansion if you determine it's appropriate to be 0.2.
Show hintHide hint
Use the principle of conservation to find outflow velocity first before calculating.
Question 6.
A system requires 0.5 meters of head loss due to minor losses from various fittings. If the total fluid velocity is 5 m/s, estimate the appropriate k_l value representing the entire system.
Show hintHide hint
Revisit your equations to ensure accuracy when rearranging for k_l.
