For NFPA 13 installations the flow per sprinkler must be the greater of:(1)the flow listed in Table C above and(2)the flow required to <br /> achieve a minimum design density of 0.1 gpm/sq ft over the design area of the sprinkler. <br /> 2. For coverage area dimensions less than those listed above,use the minimum required flow for the next larger max.coverage area listed. <br /> Bulletin 006 Rev.
