Question 2.
What does the Reynolds number indicate?
Show hintHide hint
Consider its role in different flow regimes.
3Question 3.
What does Reynolds number represent?
- Ratio of surface tension to gravity

- True
- False
Show hintHide hint
Consider the role of gravity in various fluid types.
Question 5.
Calculate the Reynolds number for a fluid flowing through a pipe with a diameter of 0.1m, a velocity of 3m/s, and a kinematic viscosity of 0.001 m2/s.
Show hintHide hint
Convert viscosity if necessary and ensure consistent units.
Question 6.
Explain how varying the viscosity of a fluid would affect the Reynolds number and the nature of flow in a pipe.
Show hintHide hint
Consider how fluid properties impact flow dynamics.
