Question

give the significance of reynolds number

Answer 1

Reynold number is a very important dimensionless quantity in fluid mechanics. It's defined as the ratio of inertial forces to viscous forces to predict the fluid flow conditions. For example, it can be used to characterize different flow regimes within a similar fluid, such as laminar or turbulent flow.

Answer 2

Answer:

The significance of Reynolds number are-

1. The Reynolds number (Re) helps predict flow patterns in different fluid flow situations.
2. Types of flow are classified into two types:a) laminar flow and b)turbulent flow.
3. Reynolds number helps us to determine whether the flow is laminar or turbulent.
4. At low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow
5. At high Reynolds numbers, the flow tends to be turbulent.
6. Reynolds number is defined by the ratio of inertial forces to that of viscous forces.

Explanation:

Reynolds number (Re)

The Reynolds number (Re) helps predict flow patterns in different fluid flow situations.

Types of flow

Types of flow are classified into two types -

1. laminar flow and
2. turbulent flow.

Reynolds number helps us to determine whether the flow is laminar or turbulent.
