For NFPA 13 installations the flow per sprinkler must be the greater of: (1) the flow listed in Table B 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 2 of 8 <br />May 2019 www.reliablesprinkler.com <br />
