WebFor internal flows, laminar flow corresponds to Reynolds number values of less than approximately 2300, where the limit may be different for external flows. In other words, a systems designer can be reasonably assured that fluid flow will be laminar as long as: The flow rate is low enough. The fluid density is low enough.
