I need a boffin or techy.
Theroretical but I would like to find the answer ,if there was a leak (say 100rms) it vapourises/expands,then mixes with air,it needs approx 1 part isobutane vapour to 9 parts air for flammability, so the 100 grams expands as a voupour mixes with air at a rate of 1 to 10,:
Wondered what would be the cubic size of this complete mixture would be.
So if 100 gram leak takes place in a room 10 meters x 5 meters would it fill it (as a flammable mixture) over flow from the room
Any help would be of great interest.
Gas Data
Atomic Weight
58.124
Boiling Temp.
-12
Vapour Pressure
(psia) @ 15°
38
Critical Temp. (°C)
135
Cond. Temp. at
26 bar abs (°C)
114
I am sure I have worked this out in the past but sadly the grey matter is slowly turning to sludge.
I know he explosion/flammable limits are between 1.5% and 15%approx mixture with air
Thanks
