vl = tonnes

[spank]

I'm trying to figur something out How many vl/tonne in ship design. I ran the numbers and i came up with about 14,285 vl per tonne. Does this sound right?

 

[DrSkull]

1 displacement ton = 14 cubic meters

1 vl = 10 liters

1 cubic meter = 1000 liters

So I'd make it:

14 x1000 /10= 1400 vl per ton

I don't have my book handy so I can't cite a page number but somewhere in there it does state how many vl are in a dTon...and I believe that DrSkull has it correct at 1400, if not, it is something very close

 

[R_Kane]

ok DrSkull is right on the money

this is stated in the top of the second column on page 223

Ok. I was using 1 vl=1 liter

thanks

Just as long as you realise that having a displacement ton doesn't mean that each DT of starship actually weighs a ton.

 

[spank]

yeah, I know I just wanted to know how big a dTonne was, a cube 2.426 meters per side i think I wish they'd called it something different like an hLiter or something

For deckplans, a displacement ton is two 1.5 meter squares (about 3 meters tall)

So a "cube" 3m*1.5m*3m

Which happens to be the volume of one ton of liquid hydrogen. That's the explanation for the use of tons for volume in spacecraft.

It's not unprecedented. Merchant ships today use "tonnage" as a measure of volume as well; one register ton is 100 cubic feet of enclosed volume.

That comes out to 13.5 cubic meters which is close to the volume of a tonne of liquid hydrogen
