| Jun 8, 2018 at 9:20 | comment | added | mart | Each branch off the main line has a regulator valve? How's the control scheme? What pressure & flow rates are we talking about (approx!)? Pressure required at the demand points? I find it confusing that your main pipe and branches are desigated d1 except the main line near pint 2 is designated d2. Can you draw a proper P&ID with all the information you have now? | |

| Jun 7, 2018 at 19:21 | comment | added | Mark | You'll want to use the Hardy-Cross Method here. (en.wikipedia.org/wiki/Hardy_Cross_method). A generalized version, using simple friction factors, would be best, so long as you don't approach within 50% of the speed of sound of air in the piping (epublications.bond.edu.au/cgi/…). You'll need to recognize that all air flowing out of the instruments is in fact going to a common outlet (the building), and will have a common pressure value (the building's air pressure), so you will have a fully connected network. | |
