WebJul 7, 2024 · 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. WebJan 26, 2024 · Whilst the critical Reynolds number for turbulent flow in a pipe is 2000, the critical Reynolds number for turbulent flow over a flat plate, when the flow velocity is the free-stream velocity, is in a range from \(10^5\) to \(10^6\). \(^4\) ...
