WebAccordingly, the value of Reynolds number (R e) can be expressed as: Note that: ρ is the density of the fluid. V is the fluid velocity. D is the hydraulic diameter (of pipe, tube, or duct). μ is the fluid viscosity. Important takeaways from the Reynolds number calculation include: ☐ A flow is considered laminar if the Reynolds number is up ...

WebThe Reynolds number in laminar flow can vary over a wide range, depending on system geometry. Laminar flow tends to occur in Reynolds number values below … WebThe type of flow is determined by a non-dimensional number called the Reynolds number for a pipe flow. Re = (VD/v) Where, D = Diameter of pipe V = Mean velocity of the flow in pipe ... If the Reynolds number is more than 4000, then the flow is called turbulent flow. If the Reynolds number is between 2000 and 4000, the flow may be laminar or ...
WebRecently, Ajeel et al. [16] performed numerical and experimental investigations in corrugated pipes with different types of nanofluids at a Reynolds number of 10,000. The summary of the previous studies related to turbulent fluid flow and heat transfer in corrugated walled pipes has been listed in Table 1. Here, Re b denotes bulk mean Reynolds ...
