How To Read Moody Diagram

If however the flow is in the turbulent range we are ready to proceed with the moody chart. If you try to solve this factor directly much complexity is experienced.

Fanning Friction Factor Wikipedia

Si based moody diagram.

How to read moody diagram. Compute the relative pipe roughness. In these cases moody diagram or moody charts are really handy. The friction factor can usually be interpolated between the laminar value at re 2300 and the turbulent value at re 4000.

This value is the roughness of the pipe. This value is the roughness of the pipe. Compute the relative pipe roughness.

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. Refer to the moody chart. Sonya lopez moody diagram at first glance three datasets in one.

Procedure as with many fluid mechanics problems the first order of business is to determine. If the reynolds number falls in the laminar or transition range refer to appropriate equations. Also remember just.

Whether the flow is steady or transient we have to use it. Refer to the moody chart. How to read the moody diagram by dr.

How to read a moody chart. The coefficient can be estimated with the diagram below. For circular pipes the problems can be solved using swamee jain equation but for the other types it is really difficult.

If the reynolds number falls in the laminar or transition range. View test prep howtoreadmoodydiagram from ce 303 at california state university los angeles. 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.
