I'm using 8.0k above and 5.6k in the pit and plenum. The booth is going in 500 ft away from the riser and there are 15 sprinklers in this booth 8 above and 7 in the pit and plenum. I'm trying to cut on down on the bulk main supplying the booth. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Randy Knutson Sent: Monday, June 15, 2009 12:06 PM To: [email protected] Subject: RE: Mixing k-factors in paintspray booths Thanks Thom. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Thom McMahon Sent: Monday, June 15, 2009 11:56 AM To: [email protected] Subject: RE: Mixing k-factors in paintspray booths NFPA 13, 2007 A.22.4.4.8 The use of sprinklers with differing orifice sizes in situations where different protection areas are needed is not considered balancing. An example would be a room that could be protected with sprinklers having different orifice size in closet, foyer, and room areas. However, this procedure introduces difficulties when restoring a system to service after operation since it is not always clear which sprinklers go where. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Randy Knutson Sent: Monday, June 15, 2009 11:42 AM To: [email protected] Subject: Mixing k-factors in paintspray booths Forum Members, Can I use a smaller k-factor sprinkler in the pit and exhaust plenum of a paint spray booth? Due to the geometry of the pit and exhaust plenum. The sprinklers in there are covering about 36 square feet per sprinkler. Any insight would be appreciated.
