Reynolds number describe the type of flow of fluid. If Reynolds number has a high value then it is called turbulent flow and if Reynolds number is low then it is called laminar flow. Reynolds number given as follows:
For internal pipe flow, if Reynolds number greater than 4000 then, it is called turbulent flow and if Reynolds number less than 2000 then it is called laminar flow. The Reynolds number between 2000 to 4000 the flow is called transition flow.
