In engineering, the Moody chart or Moody diagram is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor fD, Reynolds number Re, and relative roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe. Moody diagram showing the . A Moody diagram that can be used to estimate friction coefficients. The Moody friction factor - λ (or f) - is used in the Darcy-Weisbach major loss equation. If the flow is transient - < Re < - the flow varies between laminar and turbulent flow and the friction. Aug 10, When solving many fluid dynamics problems, be it steady state or transient, the Darcy-Weisbach friction factor, f, is necessary. Therefore, it is often effective to solve for this friction factor using the Moody Chart. If however the flow is in the Turbulent range, we are ready to.

The Moody chart is a graph in non-dimensional form that relates the Darcy- Weisbach friction factor fD, Reynolds number Re, and relative roughness for fully developed flow in a circular pipe. It can be used for working out pressure drop or flow rate down such a pipe. The Moody diagram (also known as the Moody chart) is a graph in non- dimensional form that relates the Darcy friction factor, Reynolds number, and the relative roughness. How to read Moody Diagram. In fluid dynamics we have to solve problems which involves the use of Darcy-Weisbach friction factor f. Whether the flow is steady or transient we have to use it. If you try to solve this factor directly, much complexity is experienced. For circular pipes the problems can be solved using Swamee-.

Re = Reynolds Number. The symbol Re is not the product (R)(e). Kinematic viscosity (v) depends on the fluid (water, air, etc.). Click for table. Surface roughness depends on the duct material (steel, plastic, iron, etc.). Click for table. The equations used in this program represent the Moody diagram which is the old-fashioned.
