Attention Engineers... Help please!

You need to use differential equations to solve this since the pressure is going down so you will the flow rate won't be constant. If you assume it to be constant you can convert the SLM>SCM like Linxs said.

Hmm, I was thinking about this. The gas bottle says "Final Volume: 142 SCF", but the actual volume of the bottle is say, 10 cubic feet if that. So, that 142 SCF, is that the actual volume of just the gas under some standard conditions? If so, then what Linxs is saying will be right. You see, at first, I was being completley retarded, and just assuming the bottle itself was 142 cubic feet, which is just ridiculous. I lied though, I have not had a chance to take care of this, I will soon though, and Ill let ya know what comes up Linxs... [img]tongue.gif[/img]

SCF (standard cubic foot) means one cubic foot of gas measured at 60 °F. and 14.7 psia.

Haha, duh... See, if I had realized that hours ago, I would have had this solved by then. Hey, it was still early in the morning, and I wasn't thinking, and for whatever dumb reason, read that 142 SCF as being the volume of the bottle, not the gas. Yes, im dumb... But you at least do see why I was disagreeing with you right Linxs? If that number was in reality the volume of the tank holding the gas of unknown SCF, then, it wouldnt work... Right? Or am I still sleeping...

P.S. 142 SCF is final volume at 2000 PSI. I only have 1200 psi, so Ill just assume Ill only get 5-6 days... I ordered more bottles so now im not extremley concerened about accuracy.
