Webnearly constant over a wide range of Reynolds number. The drag force on a sphere is a classic example. As seen in Figure 1 (reproduced from Reference 1), drag coefficient CD is relatively flat in the range of Reynolds number between about 10 3 and 2 105. In this range, therefore, C D can be considered nearly independent of Red. At higher ...

WebThe Reynolds number is a dimensionless number that nicely summarizes the fluid flow characteristics. For 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 ...
