    Specifics

    More specifics:  All my years in this business, I have never designed  a compressed air distribution system so my question is. I have a client with a autobody shop who needs compressed air lines to 5 hose reels, total run of  200' in a pressure balanced loop.  The compressor is on sight and it is a 100 gallon 15 H.P. unit. I expect supply pressure to be 125-150 p.s.i. What size pipe should be used for mains? is there a formula or chart available to reference?

    Thanks for any help.
