Reynold number formula is pvl/m.
Where v- velocity and l is length
That's why Reynold number is directly proportional to velocity and length.
Where v- velocity and l is length
That's why Reynold number is directly proportional to velocity and length.

Reynold number = density * average velocity * diameter ÷ dynamic viscosity. It's Reynold number formula.

Guys still I don't get how it's directly proportional to its velocity and length. Please explain me.

Turbulent or laminar flow is determined by the dimensionless Reynolds Number.
The Reynolds number is important in analyzing any type of flow when there is substantial velocity gradient (i.e. , shear). It indicates the relative significance of the viscous effect compared to the inertia effect. The Reynolds number is proportional to inertial force divided by viscous force.

Reynold's number is show of flow of water.
Example laminar and turbulent flow:
Rn<2000 laminar flow.
Rn>4000 turbulent flow.

What is Reynold's number?

Reynolds number = ratio of inertia force to viscous force.
viscous force = ((mue)*(v/L)*a.
SO IT IS DIRECTLY PROPORTIONAL TO THIS.
viscous force = ((mue)*(v/L)*a.
SO IT IS DIRECTLY PROPORTIONAL TO THIS.

Apply formula re=row*v*l/meu.
From this re is proportional to v.
From this re is proportional to v.

Re=pvl/m. p density and m absolute velocity. so Re directly proportional to v and l.
