Hello all -
I fly a good deal, and I love to share my travel experiences with my family and friends - part of which is how amazing it is that a machine can spend a minute accelerating down a runway on one side of the ocean, and ten hours later land on the other side. I was trying to put some of the facts and figures into context for a young relative, and strangely enough he went down the fuel path. I dutifully explained to him weight, volume, specific gravity, all that, and then (as kids tend to do) he asked me - 'How much fuel could this room hold.' I was stumped, because I had never thought about fuel in a volume sense, though I recall that volume varies with pressure and temperature.
Thus I pose the question to this crowd - how much volume does a given bit of fuel take, and what variables influence the translation? And, more to the point - how much volume is available on a large commercial transport (say 77E, since that was the plane in question in the conversation), and how much actually gets used vs what's 'headroom' for expansion/contraction based on those variables?
Any wisdom on this much appreciated!
