The bottom of the tanker is rounded but the cargo wagon is square so you would get a little extra space in there, not much though. 5.5k is a lot of liquid to be shipping around but you can't really argue with the numbers. The devs have plans to implement a tanker at some point, it will be interesting to see how they handle this. Even if you decrease the stack size of barrels to 5 that is still 1 storage tank per cargo wagon.
From looking at the vanilla carriage in the game (0.11.x) it looks like the top is rounded but the bottom is square.
If this is true then you gain 10.75% more volume to store liquid when converting to a cylindrical carriage of the same length.
If the vanilla carriage is completely rectangular (and no curved top) then you gain nothing.
When we convert the square bottom to rounded we lose 10.75% volume. Since only half the vanilla carriage is square we lose half our gain of 21.5%.
If we have to convert the whole carriage from rectangular to cylindrical we lose all our gains as the numbers cancel each other out.
i.e. We gain 21.5% converting from cylindrical barrels to liquid storage. Then we lose 21.5% converting from a rectangular carriage to a cylindrical one.
TLDR: It all depends on what you consider the vanilla carriage to be. If rectangular: no gain; if half round/half rectangular: +10.75%.
How much mass/volume is 1 unit of liquid here? I have no clue.
Are tanks & barrels properly balanced? Hell no. I could easily fit more oil in barrels within chests in the same area it takes to place a large tank.
If a storage chest holds 8 barrels in 48 slots (IIRC) then that's (8*48)*25 for 9600 units of liquid storage. Much much much more liquid can be stored, by volume, in a single chest than any one tank. (This is just for a 1x1 area. A tank is 3x3 so that would mean I could fit 86400 units of liquid in chests for the same space in the game.
