Graph of friction factor vs. reynolds number
WebIn term of friction factor with Reynolds number. The friction factor is inversely proportional to Reynolds number for all conditions. These results are in accordance with previous experiment [1]. WebFor hydraulically smooth pipe and the turbulent flow (Re < 10 5 ), the friction factor can be approximated by the Blasius formula: f = (100.Re)-¼. It must be noted that the friction factor is independent of the Reynolds number at very large Reynolds numbers. This is because the thickness of the laminar sublayer (viscous sublayer) decreases ...
