I have two questions
1- Is there any available publication to reefer to for hazard classification in NFAP 13, for example what define an ordinary hazard? is there statements on the expected Heat release rate ? or the excepted fire load ?
2- in designing a sprinkler system for lets say an ordinary hazard, NFPA 13 do not mention a high limitation in respect of the K-factor. is there any method to be able to determine the proper K-factor for an ordinary hazard with a high ceiling?
