Question 1.
What does head loss indicate in a fluid flow system?
Show hintHide hint
Think about energy in terms of height.
Question 2.
What equation do we use to express the friction factor in laminar flow?
Show hintHide hint
Recall the relationship for laminar flow behavior.
3Question 3.
Which equation represents the friction factor for laminar flows?
- f = Re
- f = 64/Re
- f = 1/Re
Show hintHide hint
Focus on the relationship identified in the discussion.
4Question 4.
True or False: Surface roughness decreases energy loss in fluid flow.
- True
- False
Show hintHide hint
Remember how turbulence affects flow efficiency.
Question 5.
Given a pipe with a diameter of 0.2 meters carrying water with a Reynolds number of 3000, determine the friction factor and the expected head loss for 100 meters of pipe. Use the Darcy-Weisbach equation.
Show hintHide hint
Use the provided relationships for calculations.
Question 6.
Compare the energy loss in a water pipeline made from PVC versus one made from cast iron, given that PVC is smoother than cast iron. Discuss how this affects the design considerations.
Show hintHide hint
Assess how surface characteristics influence overall efficiency.
