Dear zxc
Im not afraid of venting the gas. Because cylinder's burst disk performs at 190 bars. I want to know how should I hydraulically calculate a system stored in higher temperatures like 40, etc. according to nfpa graphs or should I generates new graphs regarding new temp.
all the best

Hi checopi
Im working on a high pressure co2 extinguishing system and nfpa 12 is its standard. Im sure about the standard but i could not to find out the standard meaning in that matter mentioned above.
Thanks for your answer.
I know about that 2 rules. But I have another question.
I just want to know about the calculation basis at temperature other than 21C.
Should I use other y and z than what mentioned in nfpa?
I think if we change the storage pressure the average discharge pressure is...
hello all.
the storage temperature of co2 cylinder is mentioned -18 to 54 in nfpa12.
on the other hand the calculation in nfpa12 is based on 21C (750psi). also nfpa says:
" this pressure has therefore been selected for calculations involving high pressure systems"
is it mean that all calculation...
