Question 1.
What are major losses in pipe flow?
Show hintHide hint
Think about long segments and friction.
Question 2.
What does the hydraulic diameter help determine?
Show hintHide hint
Focus on the geometry of the conduit shape.
3Question 3.
What primarily causes major losses in pipe flow?
- Turbulence
- Friction
- Elevation Changes
Show hintHide hint
Consider what happens between the liquid and the pipe surface.
4Question 4.
Minor losses occur at bends and fittings.
- True
- False
Show hintHide hint
Think about what happens when the flow direction changes.
Question 5.
Design a pipe system that minimizes energy losses using both major and minor loss considerations for a residential water supply. Calculate the expected losses.
Show hintHide hint
Remember to consider the characteristics of all fittings and the lengths of pipe.
Question 6.
Analyze how a change in fluid velocity impacts the energy losses in a system that uses circular versus noncircular conduits.
Show hintHide hint
Relate to the formulas for hydraulic diameter and Moody chart for friction factors.
