Show hintHide hint
Think about how syrup flows.
Question 2.
What does a Reynolds number below 2300 indicate?
Show hintHide hint
Remember the threshold for laminar flow.
3Question 3.
Is laminar flow represented by smooth parallel lines?
- True
- False
Show hintHide hint
Visualize streamline flow.
4Question 4.
What is the Reynolds number threshold for turbulent flow to begin?
- < 2300

Recall the transition points.
Question 5.
Consider a circular pipe with a diameter of 0.15 m, a fluid with a density of 850 kg/m³, and a dynamic viscosity of 0.002 Pa·s. If the average velocity is 1.5 m/s, classify the flow type and justify your answer.
Show hintHide hint
Use the Reynolds number formula.
Question 6.
Describe how you would experimentally determine if a new fluid shows laminar or turbulent behavior, detailing the setup and procedures.
Show hintHide hint
Consider how flow patterns can indicate the type.
