Question

Range of Reynold's number for the laminar flow of a liquid is______________

Answer 1

Reynold's number

1. It is the ratio of inertial force to viscous force.
2. It happens in the fluid which is subjected to relative internal movement due to different fluid velocities.
3. Its value gives us an idea of whether the flow will be laminar or turbulent.

Reynold's formula:

$Re=\frac{\rho uL}{\mu }$

where $Re$=Reynold's number

$\rho$=density of the fluid

$u$=flow speed

$L$=characteristic linear dimension

$\mu$=dynamic viscosity of the fluid

If Reynold's number is less than $1000$

Then, the flow is considered to be laminar.

Hence, the range of Reynold's number for the flow of liquid is between $0$ to $1000$
