How To Read Moody Diagram

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

Fluid Mechanics

Whether the flow is steady or transient we have to use it.

How to read moody diagram. If the reynolds number falls in the laminar or transition range refer to appropriate equations. If you try to solve this factor directly much complexity is experienced. If however the flow is in the turbulent range we are ready to proceed with the moody chart.

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. How to read the moody diagram by dr. This value is the roughness of the pipe.

Procedure as with many fluid mechanics problems the first order of business is to determine. Si based moody diagram. Compute the relative pipe roughness.

If the reynolds number falls in the laminar or transition range. Compute the relative pipe roughness. 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.

In these cases moody diagram or moody charts are really handy. Sonya lopez moody diagram at first glance three datasets in one. For circular pipes the problems can be solved using swamee jain equation but for the other types it is really difficult.

The friction factor can usually be interpolated between the laminar value at re 2300 and the turbulent value at re 4000. The coefficient can be estimated with the diagram below. Refer to the moody chart.
