Reynolds number: It is defined as the ratio of inertia force of a flowing fluid and the viscous force of the fluid.
Inertia force= Mass*Acceleration of the flowing fluid.= ρ*V*velocity.
where ρ=density of fluid and V is volume.
Viscous force= Shear stress*Area= τ*a
By definition of Reynolds number R=VL/ν.
Where ν=μ/ρ. Or
Then there is also Reynolds model law It is a law in which models are based on Reynolds number. These models include
1.Pipe flow problems
2.Resistance experienced by submarines, airplanes, fully immersed bodies etc.
