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 <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 Reliable Page 5 of 8 <br /> May 2019 www.reliablesprinkler.com <br />
