At least you are not spending money and time on BIM while all the other

ESFR's are very limited, averaging the height is not allowed. There is
also a 20 ft maximum limit for distance from the top of storage to the
roof sprinklers but I don't know if applies when there are in-rack

If it's a municipal water supply the two graphs will probably not be the
same. The graph isn't from a zero flow to the 2.5 flow and then the
4.5 flow. If there was 2,000 gpm domestic flow at the time of the test

project it would include bunch of stuff that probably isn't
