Question

The flow in a pipe is neither laminar nor turbulent when reynolds number is

Answer 1

Answer:

Whenever the Reynolds number is less than about 2,000, flow in a pipe is generally laminar, whereas, at values greater than 2,000, flow is usually turbulent.

Answer 2

Answer:

When the Reynolds number is between $2000$  and $2008$ the flow in a pipe is neither laminar nor turbulent.

Explanation:

The Reynolds number is the ratio of inertial to viscous forces inside a fluid subjected to relative internal movement owing to differing fluid velocities. A boundary layer, such as the bounding surface on the inside of a pipe, is an area where these forces alter behaviour.

• A Reynolds number is a dimensionless metric that aids in flow behaviour prediction.
• Laminar flow is indicated by a low Reynolds number, whereas turbulent flow is indicated by a high Reynolds number.
