hi
what is the relation between K factor and ceiling high in non-storage occupancies?
is there any reference about that in NFPA Book?

RE: the relation between K factor and ceiling high
What exactly are you referencing?
I ask, because there are variations to each.

mall with ceiling high of 15 m
room with 3 m ceiling high and thus
does sprinkler with K-5.6 work for different ceiling high?
RE: the relation between K factor and ceiling high
A lot depends on which Code/Standard you have to use.
Previously there was an exception that allowed sprinklers to be omitted above 55'. This dis-appeared.
I must defer to others as to current codes, but as of now,, I do not know of any allowances or restrictions with relation to K vs Height.
I know there is some real concern as to A.D.D (Actual Delivered Density), where the water droplets may not be able to penetrate a plume that high.
I have not seen any data or models.

NFPA also uses the term "non-storage" >> see NFPA-13 8.17.5.1.3(6)..
RE: the relation between K factor and ceiling high
I think it would be prudent to go with the higher k-factors that FM requires in higher ceiling areas. Afterall, NFPA 13 is a MINIMUM standard. You can always exceed the minimums.

You might want to check FM DS 2-0 (Table 3 - Page 15) for reference.
Have not come across any guideline related to Ceiling heights and K factor in NFPA though.
