How to read a moody diagram. Procedure as with many fluid mechanics problems the first order of business is to determine. Read the value of the friction factor at that intersection on the lh scale. 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.

If the reynolds number falls in the laminar or transition range refer to appropriate equations. Sonya lopez moody diagram at first glance three datasets in one. Refer to the moody chart.

It can be used to predict pressure drop or flow rate down such a pipe. This value is the roughness of the pipe. Compute the relative pipe roughness.

This value is the roughness of the pipe. The friction factor can usually be interpolated between the laminar value at re 2300 and the turbulent value at re 4000. Refer to 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. Also remember just. For circular pipes the problems can be solved using swamee jain equation but for the other types it is really difficult.

At first glance i thought it would be fairly straight forward but the courses book has an example in which it doesnt describe how to read the diagram rather it annoyingly says from the moody diagram friction factor 00053. To download the notes i use for these videos please click the following link. Si based moody diagram.

How to read the moody diagram by dr. Reading off a moody diagram watch. In these cases moody diagram or moody charts are really handy.

How to read a moody chart. 1 report thread starter 3 years ago 1 i have to determine the friction factor. An introduction to the famous moody chart.

The coefficient can be estimated with the diagram below. We use the moody chart often to estimate frictional factors. If the reynolds number falls in the laminar or transition range.

In engineering the moody chart or moody diagram is a graph in non dimensional form that relates the darcy weisbach friction factor f d reynolds number re and surface roughness for fully developed flow in a circular pipe. Start new discussion reply. If you try to solve this factor directly much complexity is experienced.

Compute the relative pipe roughness. If however the flow is in the turbulent range we are ready to proceed with the moody chart. Whether the flow is steady or transient we have to use it.
