As the Reynold's number increases the friction factor increases in turbulent flow.

The turbulent fluid is the flow of liquids in which it does not flow in parallel layers and there is a disruption between the layers

Here the lateral mixing is very high.
There is also a disruption between the layers.
The Reynolds number (R e) is a measure of the ratio of inertial forces to viscous forces in a fluid flow.
It is a important parameter to determine whether the flow is turbulent or laminar.
laminar flow occurs at low Reynolds numbers
Turbulent flow occurs at high Reynolds number.
The Reynolds Number is dimensionally represented as $M^{0} L^{0} T^{0}$ .
If the Reynolds number is greater than 3500, the flow is turbulent.
If the Reynolds number is less than 2000, the flow is laminar.
The accepted transition Reynolds number for flow in a circular pipe is 2300.
The friction factor is representing the loss of pressure of a fluid in a pipe due to the interactions in between the fluid and the pipe.
There are two common friction factors in use, the Darcy and the Fanning friction factors.
