The Reynolds number is generally use to determine whether the flow is laminar or ,turbulent,. The Reynolds number is based on the length scale of geometry (length or ,hydraulic diameter, for internal flow) velocity of fluid and viscosity of fluid. Transition to turbulence varies depending on the type of flow.
