PipeFlowMoodyDiagramThe Moody Diagram is widely used to determine the friction factor for fluid flow in pipes. The diagram combines the effects of Reynolds number and relative roughness to determine the friction factor. The relationship is highly non-linear and appears to have a complex interaction...

Darcy Friction Factor Formulae in TurbulentPipe FlowJukka KiijärviLunowa ∗ Fluid Mechanics Paper 110727July 29, 2011AbstractThe Darcy friction factor in turbulent pipe flow must be solvedfrom the Colebrook equation by iteration. Because of the iterationnew equations to solve this friction factor...
Pipe flow calculations include using Reynolds number to find if the flow is laminar flow or turbulent flow. Frictional head loss can be found using the Darcy Weisbach equation and the friction factor. The entrance length for fully developed flow can be found for turbu...
The following formula is proposed to provide a combined factor of safety for the latter situation: (4-1)FOScombined=(FOSlateralcosθ)2+(FOSaxialsinθ)2 where FOScombined: combined factor of safety (FOS); FOSlateral: lateral FOS; FOSaxial: axial FOS; θ: angle of mooring line from ...
The friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against theReynold's number. The blue lines plot the friction factor for flow in the wholly turbulent region of the chart, while the straight black line plots the friction factor for flow in the wh...
Integral flow quantities, such as the total volumetric flow rate of the gas, the solids loadings, the pressure drop, and the friction factor of the flowing mixture may be readily computed from this model. The friction factors obtained via the entropy production method agree very well with ...
