In a pipe flow, the critical Reynolds number is 2300. Critical Reynolds number is related to the laminar-turbulent transition wherein laminar flow becomes turbulent.

Answer: In pipe flow, the critical Reynolds number is about 2300.
The ratio of inertial forces to viscous forces is known as the Reynolds number. For different geometries, the value of the Reynolds number is different. With the help of the Reynolds number, the flow pattern in different fluids can be determined. When the value of Reynolds number is less than 2000 then it will be laminar flow whereas, for the transitional flow, the value of Reynolds number lies between 2000 and 4000. The flow is called turbulent when the Reynolds number is greater than 3500.
Summary:
What is the Critical Reynolds Number in Pipe Flow?
In pipe flow, the value of the critical Reynolds number is about 2300. The value of the Reynolds number helps in determining the pattern of the flow in different fluids.
