Hello everyone
I was designing a sprinkler system for a storage area that has a max height of 10 ft (3m). Before this i have designed various warehouses where height was always more than 20 ft but here i have to refer to NFPA 13(2016 ed) chap 13 wherein i get the OH2 specs for my storage area(class IV on racks). density chosen on curve is 0.2 gpm/ft2 and the total area of my storage is only 1250 sq ft. I want to know any what K factor sprinkler should i use with what discharge pressure with references. I was looking at FM datasheets and from there it seems i will have to take k 14 with 12 sprinklers designed at 50 psi, but this seems very overdesigned to me. Please help clear this out for me. Attached file is the FM data sheet referred.
