Oxygen friction loss calculation?

[jgreg43]

Does anyone have the formula to calculate Oxygen - I want to know the friction loss if given the LPM and the pipe size.

I was trying to work with a chart in a spreadsheet and am running into more problems, so I wanted to get the actual friction loss for size of pipe given the LPM.

For 100' of pipe or a given length of pipe

jgreg43:

Read thoroughly and apply the fluid flow relationships given in Crane's Tech Paper #410. There, you will find that the Darcy-Weisbach equation is valid for gases such as Oxygen - as long as you don't exceed a pressure drop larger than 10% of the intial pressure.

You can certainly set up the exercise in a Spreadsheet; I have, and so have countless other engineers that I've worked with. Good luck.

Contact a medical gas vendor and they have tables and charts used for oxygen.

Some that I use are Beacon-Medaes and Amico.

What are the problems other than following suggestion of
