Question

the reynolds number for fluid flow in a pipe is independent of ​

Answer 1

Answer:

Laminar Flow in a Pipe

Laminar flow occurs when the calculated Reynolds number is less than 2300 and in this case the resistance to flow is independent of the pipe wall roughness.

Answer 2

The reynolds number for fluid flow in a pipe is independent of ​ turbulent flow through rough pipes

Explanation:

The Reynolds number for the fluid flow is given by :

$R=\dfrac{\rho vl}{\mu}=\dfrac{vl}{\nu}$

Here,

v is velocity of fluid

l is characteristics length

$\rho$ is density of fluid

$\mu$ is dynamic viscosity of the liquid

$\nu$ is the kinematic viscosity

• It is clear that, in fully turbulent flow through rough pipes friction factor is independent of Reynolds number.
