The flow regime (either laminar or turbulent) is determined by evaluating the Reynolds number of the flow refer to (Flow Velocity profiles). TheReynolds number, based on studies of Osborn Reynolds, is a dimensionless number comprised of the physical characteristics of the flow. Equation 1 is use...
Reynolds Number can then be calculated using equation (1) likeRe = (910 kg/m3) (2.6 m/s) (25 mm) (10-3 m/mm) / (0.38 Ns/m2) = 156 ((kg m/s2)/N) = 156 ~ Laminar flow 1 (N) = 1 (kg m/s2) Related Mobile Apps from The Engineering ToolBox ...

输气管的雷诺数一般高达106~107,是输油管的10~100倍。The Reynolds number of the pipeline is generally as high as 106~107, which is 10~100 times that of the pipeline.
In this paper a calculation of the normal fluid heat-exchange drag is given which is valid for low (stream) Reynolds number. The basic differential equation of the theory must be solved numerically. However, an approximate result is given, valid for low (heating) Reynolds number 关键词: ...
the problem is solved by a technique involving the matching of biorthogonal infinite eigenfunction expansions in different parts of the domain. Truncated versions of these series are used to compute a finite number of unknown coefficients. In this way, the stream function and its derivatives can be...
