There isnt one.  Years ago FM used 25-fps but I'm pretty sure it's no longer in 
the FM Data Sheets.  It's still a good rule-of-thumb though.  Some plumbing 
designers use 32-fps as a max velocity.  Much faster than that and certain 
piping configurations can produce cavitation (imagine the sound of a 
continuously flushing toilet).  
   
  I'm sure others out there will have a more precise answer for you.

  Would anyone be able to give me any info on the max velocity for
sprinkler piping? If so, can you give me a code section it would be
under?
