Moody Friction Factor Calculator – LMNO Eng

The Moody friction factor (f) is used in the Darcy-Weisbach major loss equation. Note that for laminar flow, f is independent of e. However, you must still enter an e for the program to run even though e is not used to compute f. Equations can be found in Discussion and References for Closed Conduit Flow.

CalcTool: Darcy friction factor calculator

Note that the Darcy friction factor is directly related to the Fanning friction factor (which is 1/4 of the Darcy factor). In pure laminar flow, the Darcy factor can be taken as 64/Re (Reynolds number), but when the Reynolds number is above ~2300, turbulent flow means that an approach such as the Colebrook equation must be used.

Friction Factor Calculations – Pipe Flow Software

Friction Factor Calculations The Darcy-Weisbach equation, for calculating the friction loss in a pipe, uses a dimensionless value known as the friction factor (also known as the Darcy-Weisbach friction factor or the Moody friction factor) and it is four times larger than the Fanning friction factor.

Use the Friction Factor to Calculate Frictional Head Loss

The friction factor (also sometimes called the Moody friction factor) can be determined for known values of Reynolds number and ε/D from empirically derived charts and/or equations. A commonly used chart is the Moody friction factor chart, shown in the diagram on the left.

Colebrook Equation – Engineering ToolBox

The Colebrook equation is generic and can be used to calculate friction coefficients for different kinds of fluid flows – like air ventilation ducts, pipes and tubes with water or oil, compressed air and much more. Colebrook Online Calculator. The friction coefficient can be calculated with the online Colebrook calculator below.

Pipe Friction Calculation for Fluid Flow in a Pipe

The calculator above first computes the Reynolds Number for the flow. It then computes the friction factor f by direct substitution (if laminar; the calculator uses the condition that R < 3000 for this determination) or by iteration using Newton-Raphson (if turbulent). The pressure drop is then calculated using the viscous head equation above.
