Consider the following statements:
1. At low Reynolds numbers of any flow, viscous forces dominate over inertial forces. 2. Transition from laminar to turbulent flow occurs over a range of Reynolds number depending on the surface presented to the flow.
Which of the above statements is/are correct?
  • a)
    1 only
  • b)
    2 only
  • c)
    Both 1 and 2
  • d)
    Neither 1 nor 2
Correct answer is option 'C'. Can you explain this answer?

Consider the following statements:1. At low Reynolds numbers of any f...
Reynolds number is the ratio of inertial force to viscous force. So for low Reynolds number, viscous force > inertial force. The critical value of Reynolds number depends on the surface on which the flow occurs. So both the statements are true.

Explanation:

Viscous Forces vs. Inertial Forces:
- The statement "At low Reynolds numbers of any flow, viscous forces dominate over inertial forces" is correct.
- Reynolds number is a dimensionless quantity that determines the relative importance of viscous forces to inertial forces in a flow.
- At low Reynolds numbers, viscous forces are dominant because the fluid flow is characterized by smooth, orderly movement with minimal turbulence.
- In such cases, viscous forces play a significant role in determining the behavior of the flow.

Laminar to Turbulent Transition:
- The statement "Transition from laminar to turbulent flow occurs over a range of Reynolds number depending on the surface presented to the flow" is also correct.
- The transition from laminar to turbulent flow is influenced by factors such as the roughness of the surface, flow velocity, and fluid properties.
- As the Reynolds number increases, the flow may transition from laminar to turbulent, causing an increase in chaotic motion and mixing within the fluid.
- The specific Reynolds number at which this transition occurs can vary depending on the specific conditions of the flow.

Conclusion:
- Both statements are accurate in describing the behavior of fluid flow at different Reynolds numbers.
- Viscous forces dominate at low Reynolds numbers, while the transition from laminar to turbulent flow is dependent on various factors and occurs over a range of Reynolds numbers.
