I have a question about collectors piping at spray system fire fighting.
actually, we have a collector at piping with many outlet of it and I want to understand about calculation of them please follow under line:
1-How can I calculate volume of collector pipe according number of outlet of it?
2-How can I calculate length of collector pipe according number of outlet of it?
3-what is min or max length between two outlet pipe from collector?
3-Do we have standards about it that mention calculate collectors for example at NFPA???
Generally I want know about collector piping according standard on the other hand I have searched about it in NFPA13,14,15 but I can't find that.
