# 31 How To Read Moody Diagram

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. Compute the relative pipe roughness.

### To determine the frictional factor find the relative roughness value for the pipe on the right. How to read moody diagram. If however the flow is in the turbulent range we are ready to proceed with the moody chart. To download the notes i use for these videos please click the following link. 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.

How to read a 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. Follow the curve contours in the left.

If the reynolds number falls in the laminar or transition range refer to appropriate equations. Say we are calculating a reynolds number having value of 4x104. We have to follow this line our reynolds number from before.

How to read a moody chart moody diagram procedure. This reynolds number indicates the turbulent flow. We use the moody chart often to estimate frictional factors.

As with many fluid mechanics problems the first order of business is to determine. How do you read moodys diagram. Si based moody diagram.

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. The friction factor can usually be interpolated between the laminar value at re 2300 and the turbulent value at re 4000. Then locate the pipes reynolds.

An introduction to the famous moody chart. Now follow the image. Refer to the moody chart.

You have to mark that point. Select a relative roughness 0003. So lets get into the moody chart.

The coefficient can be estimated with the diagram below. Other things to be aware of. This value is the roughness of the pipe.

Both the reynolds number. Lets imagine we calculate a reynolds number of 4x104 yes im rigging for simplicity. Using a Moody Chart - YouTube Moody diagram.
