WebAug 11, 2024 · For laminar flow, the Darcy friction factor equation is simple: f_\text {laminar} = \frac {64} {Re} f laminar = Re64 Where Re Re is the Reynolds number: Reynolds number is a function of pipe geometry, fluid velocity, viscosity, and density. You can calculate the latter with Omni's density calculator. WebMar 5, 2024 · 3.2: The Darcy-Weisbach Friction Factor. The value of the wall friction factor λ l depends on the Reynolds number: For laminar flow ( R e < 2320) the value of λ l can be determined according to Poiseuille: For turbulent flow ( R e > 2320) the value of λ l depends not only on the Reynolds number but also on the relative roughness of the pipe ...
WebSep 11, 2024 · The friction factor for laminar flow is calculated by dividing 64 by the Reynold’s number. Friction factor (for laminar flow) = 64 / Re ; This is for circular pipes. For Non-Circular Pipes; f=k/Re ; where k lies between 48 to 96. Note : When the fluid flows in a pipe and the value of Reynolds number is below 2300 the flow is considered as ... WebJun 1, 1992 · The Reynolds number (Re) was varied between 200 and 50000 to provide data for the laminar, transition and turbulent flow regimes. Nine enhanced tubes were tested. For the spirally fluted tubes, it is established that the friction factor and Nusselt number in laminar, transitional and turbulent flow are generally higher than the smooth …
WebIn chemical engineering, the following definition of Fanning friction factor is popular [1]: f ¼ F k =ðAKÞ ð1Þ where F k is the force on the object due to relative motion between object and fluid, A is the characteristic area (usually wet- ted surface area), K is the kinetic energy per unit volume and f is the friction factor.
WebIn evaluating the friction factor, it is important to determine if the flow is laminar or turbulent. If the Reynolds number is larger than 3500, the flow will be turbulent.
