Well, it can't be entirely fixed whether the Re range under which the flows are classified. In convention, for internal flows,

Re < 2000 is regarded to be laminar

2000 < Re < 4000 is regarded to be transitional flow

Re > 4000 is most often turbulent.

On the other hand, for external flows,

Re > 5E5 is said to be turbulent
