A flow of liquid is streamline, if the Reynolds' number is

If the flow is stream lined then Reynolds number is less than

In a streamline flow

What is Reynold's number ?

Assertion: Reynolds number determines the nature of flow of a liquid through a pipe. Reason: For streamlined flow, the critical velocity should be as small as possible.

Terminal velocity || Reynold number

For turbulent flow, the value of Reynolds number is
