For NFPA 13 installations the flow per sprinkler must be the greater of:(1)the flow listed in Table E above and(2)the flow required to achieve a <br /> 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 Reliable Page 6 of 8 <br /> June 2021 www.reliablesprinkler.com <br />
