Weight of fuel

Cheers dude , Is this gospel ?

Im bordering on the weight threshold so I have to account for everything

I think it varies quite a bit depending on composition but it sounds about right. I'm not sure how much the composition gets changed throughout the seasons in this country but winter diesel will be slightly less dense (using shorter chains to prevent waxing).

yeah specific gravity of diesel is 0.86 (although it does depend on the mix to some degree) and pterol is about 0.73. Pure Water at 4degrees C is the baseline of 1.00 and 1litre of water weighs 1kg. That's why a cubic metre of water weighs a tonne (there being a thousand litres in a cubic metre)

a quick google gives Specifc gravity of various oils and fuels. I konw that Iodine has a very very high specific gravity- up around 5- which means a cubic metre of iodine weighs 5ton! anyone know of anything denser (ignoring metals and metalhalides)?

As Pugwash states 860g per litre diesel, but we use 760g per litre for Unleaded petrol. This is at 4 degrees, at government approved pump mix.

We use these figures for building boats and all of the major governing bodies for boat safety and insurance reconise these figures (Lloyd Register, DNV, Maritime Coastgaurd Agency etc..)

Jim, great link.

OT, yes Iodine is pretty dense but looking through my old data book (because I was interested to see if I could find anything as nothing sprung to mind) I've found a couple of other non metal containing compounds that are more dense than molecular Iodine:

- SiCl4 = 7.59 g/cm3 @ 203K

- The Xenon fludides and oxide are close at between 4 and 5 g/cm3 but these don't really count

- Tetraiodomethane (CI4) is quite close @ 4.32 g/cm3

- Astatine should higher too but there isn't a figure for it. Again, it doesn't really count as its not a readily available chemical.

well a drum of antifreeze (assuming it is neat Triethylene glycol- which it isn't, but i haven't a clue what goes in it) would weigh 256kg whereas a drum of engine oil would weigh around 184kg. A considerable difference and probably the heaviest thing you haev in the car unless you routinely carry around barrels of Treacle (hmmmmmmmmm treacle) which is 1.5 times heavier, or Sulphuric acid which is twice as heavy as water!
