What we use for "ROUGH" calculations for bidding purposes only is the Appendix A thru H in the Fire Protection Hydraulics and Water Supply Analysis, by Pat D. Brock. Each appendix is a different material and they have the friction loss and velocity per LF of pipe at a specific "C" and flow. Again OK for bidding, not for design which we use a full Hydraulic calc.
These tables won't work with some of the "Flo" pipes but you can get pretty much the same info from the pipe MFG. If you are doing design, and don't have a Hydraulics program, save your company a lot of money and buy one. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

Usually all light and ordinary hazard.
