Question 1.
What is laminar flow?
Show hintHide hint
Think about orderly movement in a straight line.
Question 2.
Define major losses in pipes.
Show hintHide hint
Consider energy lost in a long pipe.
3Question 3.
What is the primary cause of major losses in pipe flow?
- Viscous shear stress
- Minor fittings
- Turbulence
Show hintHide hint
Consider how fluids interact with the pipe walls.
4Question 4.
True or False: The Darcy-Weisbach equation is used to calculate energy losses in pipes.
- True
- False
Show hintHide hint
Think about how *friction* relates to *energy loss* in flow.
Question 5.
A system of pipes with varying diameter is delivering water at a rate of 100 liters per minute. If the Darcy friction factor averages at 0.02, determine the total head loss across a 50-meter length. Assume the diameter starts at 0.1 meters and reduces to 0.05 meters by the end.
Show hintHide hint
Utilize both integral calculus for averaging along length and specific equations to evaluate values.
Question 6.
In a pipe network, the outlet diameter is expanded significantly, leading to turbulent flow. If you have a constant flow at a velocity of 3 m/s, discuss how you would transition your analysis from laminar to turbulent flow calculations.

Use the critical Reynolds number for reference in your derivation.
