Question 1.
What are friction losses due to?
Show hintHide hint
Think about how different surfaces interact with fluid.
Question 2.
Define minor losses in pipe systems.
Show hintHide hint
Consider what happens during a turn in a pipe.
3Question 3.
What is the primary source of friction losses in pipes?
- Pipe length
- Surface roughness
- Fluid viscosity
Show hintHide hint
Think about what the surface of a pipe might do to a moving fluid.
4Question 4.
True or False: Minor losses are always negligible in pipe systems.
- True
- False
Show hintHide hint
Consider both major and small components' contributions.
Question 5.
Design a piping network for a small town that supplies water from a river. Consider friction losses and energy gradients in your calculations.
Show hintHide hint
Sketch your network and consider different pipe diameters and lengths.
Question 6.
Given two reservoirs with a height difference of 10m connected by pipes of differing lengths and diameters, how would you calculate flow rates considering energy losses?
Show hintHide hint
Use flow continuity and energy equations to analyze.
