Compressed Air Sizing

Hello,

I am currently sizing a Compressed Air Network (Compressor CFM, HP, and Line Sizing) for a plant which has air service stations and pumps that are run by air. There are 13 Oil Supply Pumps (80 CFM @ 75 PSI each), 20 Waste Oil Return Pumps (40 CFM @ 75 PSI), and 31 air service stations (38 CFM @ 100 PSI each used for impact guns, for example).

How would I size the CFM required for the Compressor taking into account different facors like: Simultaneous Factor, Variability Factor, and Usage Factor?

Also, I really am having a hard time sizing the piping for each branch. Can somebody explain to me how to do it knowing the CFM at the compressor? I am very new when it comes to compressed air and was wondering if there was an online example, tutorial, or reference I could base myself on.

I uploaded the proposed layout for the compressed air network and compressor size calculation. I would like to use Steel as the pipe type. Any suggestion would be appreciated. Some sample calculations or methodolgies based on the drawing would also be appreciated to get me going.


Thank you.
