Mario: Given all that has been said on this forum, in addition to Roland's dissertation, I have to ask why the 20 fps limitation?
If we engineers are going to require such a limitation, I believe we have to be ready to defend it. (this holds true to anything we write in our specifcations Mark A.

I believe NFPA 15 does require velocities pressures. Anyway, I was always taught that good engineering practices restrict velocities pressures to a maximum of 32 fps in branchline piping. Hope this helps. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ivan Cabrera Sent: Tuesday, January 09, 2007 4:58 PM To: [email protected] Subject: max velocity Would anyone be able to give me any info on the max velocity for sprinkler piping?
