Moody's Friction Factor - an overview | ScienceDirect Topics The Weymouth equation, however, is of use in designing gas distribution systems in that there is an inherent safety in over predicting pressure drop (Maddox and Erbar, 1982). In practice, the Panhandle equations are commonly used for large-diameter, long pipelines where the Reynolds number is on the flat portion of the Moody diagram.

PDF Pipe Flow-Friction Factor Calculations with Excel Weisbach equation, it is more convenient to use equations for the Moody friction factor, f, rather than a graph like the Moody diagram. There are indeed equations available that give the relationships between Moody friction factor and Re & ε/D for four different portions of the Moody diagram. The four portions of the Moody diagram are: i ...

Friction Factor & Moody Chart - The Engineering Concepts Friction Chart or Moody Chart. The value of f, Darcy friction factor is taken from Moody Diagram. 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.
