How To Read A Moody Diagram

If the reynolds number falls in the laminar or transition range refer to appropriate equations. Get the line which matches your relative roughness on the right side of the chart.

Moody Chart An Overview Sciencedirect Topics

How to read a moody diagram. How to read the moody diagram by dr. Sonya lopez moody diagram at first glance three datasets in one. The friction factor can usually be interpolated between the laminar value at re 2300 and the turbulent value at re 4000.

Si based moody diagram. Refer to the moody chart. You can take a pencil a draw one for ease of using.

Refer to the moody chart. Compute the relative pipe roughness. This value is the roughness of the pipe.

If you dont get a printed line available then assume a line parallel to nearest match of that relative roughness. How to read a moody chart. How to read moody diagram simulation fouling in axial flow pressor using a throughflow supplies for alcohol ink painting what do i need to create an alcohol ink painting you need these three things 1 your hands 2 alcohol ink and 3 something to paint on yes its.

If however the flow is in the turbulent range we are ready to proceed with the moody chart. If the reynolds number falls in the laminar or transition range refer to appropriate equations. Compute the relative pipe roughness.

The coefficient can be estimated with the diagram below. This value is the roughness of the pipe divided by the diameter of the pipe. On the moody chart the friction factor is shown on the left hand y axis the reynolds number is shown on the x axis and the relative roughness is shown on the right hand y axis.

If the flow is transient 2300 re 4000 the flow varies between laminar and turbulent flow and the friction coefiicient is not possible to determine. In fluid mechanics the moody chart or moody diagram is a graph which relates the darcy weisbach friction factor f d reynolds number re and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.

If however the flow is in the turbulent range we are ready to proceed with the moody chart. A moody chart is commonly used by engineers to calculate the darcy weisbach friction factor which is then in turn used to calculate headpressure loss due to friction in pipes. Moody chart or moody diagram.
