Thanks Jeff. I saw some earlier errata on the ESFR tables and this looked skewed to me. I went and looked through the FM Global data sheets and it made somewhat more sense to me.

I notice in exposed unexpanded 35ft storage in 40ft building section there is a big penalty for using 25.2k sprinklers. 14.0k at 75psi ~ 121gpm 16.8k at 52psi ~ 121gpm 25.2k at 50psi ~ 178gpm For the same heights with cartoned unexpanded, the numbers are the same with the exception of 25psi for the 25.2k. I checked the errata for NFPA 13 2010ed and didn't see anything. Randy Knutson, CET Sales Manager Shilo Automatic Sprinkler, Inc.
