Question 1.
Define Reynolds Number.
Show hintHide hint
Think about how this number relates to flow types.
Question 2.
What are major losses in pipe flow?
Show hintHide hint
Focus on the continuous flow in the pipe.
3Question 3.
What is the significance of the Reynolds number?
- It affects fluid temperature
- It determines flow type
- It measures fluid density
Show hintHide hint
Remember the thresholds of 2300 and 4000.
4Question 4.
True or False: Minor losses are negligible compared to major losses.
- True
- False
Show hintHide hint
Think about how fittings can alter flow dramatically.
Question 5.
You have a pipeline supplying water for a residential area. It has both straight sections and bends. Propose a design that minimizes energy losses with given dimensions and demands.
Show hintHide hint
Think about the hydrodynamics of fluid flow.
Question 6.
Given a Reynolds number of 5000 and a relative roughness of 0.02, calculate the friction factor using the Moody chart.
