Question 1.
What is the main difference between laminar and turbulent flow?
Show hintHide hint
Think about how fluid layers move in each case.
Question 2.
What does Reynolds number indicate?
Show hintHide hint
Recall the threshold values we discussed.
3Question 3.
What type of flow occurs when the Reynolds number is below 2000?
- Reynolds Flow
- Laminar Flow
- Turbulent Flow
Show hintHide hint
Think about how layers of fluid interact.
4Question 4.
True or False: Turbulent flow is beneficial for mixing fluids.
- True
- False
Show hintHide hint
Consider how turbulent flow behaves compared to laminar flow.
Question 5.
Determine the diameter of a rough pipe if the average velocity is increased by a factor of 1.5 at a distance of 2 centimeters from the wall compared to a 1 centimeter distance.
Show hintHide hint
Start by applying the velocity ratios discussed and solve the resulting equations.
Question 6.
Design a test setup to measure the transition point from laminar to turbulent flow using a water reservoir and flow meter.
Show hintHide hint
Consider how you will collect and analyze the data.
