Identify the incorrect statement regarding Reynold's number
- A for , flow is laminar
- B for , flow is steady
- C for , flow is turbulent
- D is a dimensionless number
Answer & Solution
Correct Answer
(B) for , flow is steady
Step-by-step Solution
Detailed explanation
The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behaviour is known as a boundary layer, such as the bounding surface in the…
