I totally agree to that in principle, but why then in theory are the results not the same?
I've read of people (& have experienced personally) having problems with the small MAPP cannisters when they get down to 1/2 full & having to prop them into a bowl of warm water to get the required delivery pressure & yet with a 20lb cylinder the opposite seems to be true.
Just as a matter of interest, I seem to recall the person I dealt with regarding my cylinder mentioned it running at around 197 PSI when it was full & at around 120 when it got down to half full.
Chemistry & physics are not my strong points & I'll happily leave that to the experts.
