Question 1.
What is the Reynolds number range for laminar flow?
Show hintHide hint
Think about the boundary for laminar flow.
Question 2.
Define turbulent flow.
Show hintHide hint
What happens to the fluid in turbulent flow?
3Question 3.
What is the Reynolds number range for laminar flow?
- Below 2100
- 2100-4000
- Above 4000
Show hintHide hint
Where does laminar flow lie compared to turbulent flow?
4Question 4.
True or False: Turbulent flow has a clear and defined dye streak.
- True
- False
Show hintHide hint
Recall how dye behaves in both flow types.
Question 5.
A circular pipe has a diameter of 0.025 m, with water at a temperature of 20°C. Calculate the maximum flow velocity for laminar flow.
Show hintHide hint
Substitute known values carefully into the Reynolds number formula.
Question 6.
During a systematic check, you find that increasing the temperature of fluid lowers its viscosity. Explain how this impacts flow type and Reynolds number.
Show hintHide hint
Think about how temperature changes affect fluid behavior.
