the 2010 edition added the allowed K-factors HIDDEN in 8.13.2. I
submitted a proposal to have this moved to chap 12 but no success.

This is one of those times when you're challenged and you just can't
find the info.
I've hunted and hunted but can't find anything stating anything
other than the minimum of 30 psi for the in-rack sprinklers.
We are 27 ft high storage, 45 ft high ceilings, encapsulated, Class
IV commodity, multi-row racks which are 12 ft deep and back to back,
13 ft aisles.
I've got the info that 14 heads need to be calculated per
16.3.4.3.3(4) at not less than 30 psi (16.3.4.3.1)
I'm also looking at similar conditions but no greater than 25 ft
high storage.
All references are NFPA 13, 2007.
