90k sq ft changes things... For buildings over 80k sq ft, you do 500+500+250
*7.10.1.1.3 *The minimum flow rate for additional standpipes shall be 250 gpm (946 L/min) per standpipe for buildings with floor areas that do not exceed 80,000 ft2 (7432 m2) per floor. For buildings that exceed 80,000 ft2 (7432 m2) per floor, the minimum flow rate for the additional standpipes shall be 500 gpm (1893 L/min) for the second standpipe and 250 gpm (946 L/min) for the third standpipe if the additional flow is required for an unsprinklered building.

I really don't know if it should be I or III. No sprinklers and - oh, 90,000 sq ft. Current code. I'm thinking 500 + 250 until 1,250 but I can't see that in 14 anymore. Old age setting in again? Thanks for the help. On Aug 12, 2015, Vince Sabolik <[email protected]> wrote: Hello Forum -- I have a building with a dry, manual standpipe fed from an FDC. There are six standpipes with 2½" valves. Can someone break down the NFPA flow requirement, Barney-style for me? I'm thinking 500 gpm first and 250 gpm each additional. My question is how many additional? I guess they should put more pictures in the code! thanks, Vince West Tech Fire Protection, Inc. 11351 Pearl Road / Strongsville, Ohio 44136 Phone 440 238-4800 Fax 440 238-4876 Cell 440 724-7601 _____________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org - Somehow, this made it through Verizon Wireless and got to you! _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
