I AM 8' OFF SIDE WALL AND 17'6 OFF FAR WALL. WITH A HSW
BUT SINCE ROOM IS LESS THAN 800 SQFT. I CAN USE THE ACTUAL ROOM SQUARE FOOTAGE. WHICH IS 210 SQFT. WHICH THEN SAYS 21.0 GPM. THEN DETERMINE PSI WITH WHATEVER K-FACTOR IS CHOSEN. COMPARE THE 21 GPM TO THE LISTED REQUIREMENTS AND USE THE GREATER OF THE 2. ANYONE DISAGREE?

Assuming you stretch the spacing to 18’ x 18’ your math is correct. But you don’t have to assume maximum listed areas of coverage, you use the actual S x L. If a residential sprinkler is spaced so that its area of coverage is 14’ x 16’-9”, you have to use a sprinkler that’s listed up to 18’ x 18’, but you would calculate the discharge at 23.45 gpm.

I WAS GOING TO USE 18x18 4.9 K SPRINKLER REQUIRES 17 GPM @ 12 PSI FOR .05 DENSITY BUT SINCE NFPA #13 WOULD I BE REQUIRED TO DESIGN TO THESE NUMBERS. 32.4 GPM @ 43.72 PSI? OR AM I MISSING SOMETHING.
