WebThe Reynolds number is used to determine whether a fluid is in laminar or turbulent flow. Based on the API 13D recommendations, it is assumed that a Reynolds number less than … WebFor example, the commonly-cited critical Reynolds number for fluid flow in a pipe is 2300. It is not as if the flow is purely laminar at Re = 2299.99 and then purely turbulent at Re = 2300.01. However, as we cross this particular Reynolds number, the flow behavior begins to transition from laminar into turbulent.
