Thank you, Scot. For worse case scenario purposes, I applied .40 using the K-11.2 per Table 23.7 and calc'ed it along with my inside RA to be sure it would work for pricing purposes. It calc'd just fine since the engineer is requiring a max. water flow velocity of 20fps. Had to tweak my mains just a bit to lower my velocity but it works.
Can anyone guess what my first question will be to the engineer in the Pre-bid Meeting next week? Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.

A.S. over many combustible liquids. Since it is confined to a small pit, I would be *more than comfortable *with this application rate of water-only agent. This applicaton will not put our fire out, but it will keep things cool till foam or dry-chem puts the kabosh on it. Be sure to interface with the GC about drainage. If none, fine. If there is drainage, have a P-trap in the drain so fire doesn't pass down and continue the same.
