WebA Moody Chart (or Moody Diagram) is a diagram used in the calculation of pressure drop or head loss due to friction in pipe flow. More specifically, a Moody diagram is used to find the friction factor for flow in a pipe. Friction factor is plotted vs. Reynolds number and relative roughness on a Moody chart.

WebThe most common method to determine a friction factor for turbulent flow is to use the Moody diagram. The Moody diagram (also known as the Moody chart) is a log-log plot of the Colebrook correlation that relates the Darcy friction factor, Reynolds number, and the relative roughness for fully developed flow in a circular pipe.

WebThe term friction loss (or frictional loss) has a number of different meanings, depending on its context.. In fluid flow it is the head loss that occurs in a containment such as a pipe or duct due to the effect of the fluid's viscosity near the surface of the containment.; In mechanical systems such as internal combustion engines, the term refers to the power … 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 ...
