Reynold no is the criteria to determine whether the flow is laminar or turbulent. It is the ratio of inertia force to viscous force.

Reynolds no: Inertia force/viscous force.
Mach no: Inertia force/elastic force.
Euler's no: Inertia force/ pressure force.
Weber no: Inertia force/surface tension force.
Froud no: Inertia force/gravity force.
