Recently, I have a question in my mind about fluid wagon, and I wanted to make a mod about that. But then I found this post, which reminds me that my mod may also need to change the barrels...
If I understand correctly, this post is about barrels being OP when compared with fluid wagon.
But what if the fluid wagon itself is already OP?
I have seen long trains that have more than 4 cargo wagons for transporting ores from outposts. But I have rarely seen trains with more than 2 fluid wagons.
Maybe the fluid wagon is too large, such that only 1 or 2 are needed for each outpost?
And it sounds ridiculous that you can actually put 3x fluid from a stationary storage tank to a mobilized fluid wagon. Their graphical appearances just don't match this mechanic.
OK, let's do some math...
Cargo wagon vs steel chest:
Material: 845s 140 iron ore vs 280s 40 iron ore
OK, most of us don't care about resources because it is not our planet.
Size: 2x6 vs 1x1
Slots: 40 vs 48
So, the size of a cargo wagon is 1200% of that of a steel chest, yet a wagon can hold only 83.33% items of a chest.
If we say a steel chest has 100% efficiency, than, a cargo wagon has only (40 / (2x6)) / ((48 / (1x1)) = 6.944% efficiency.
I'm not saying it is a problem. It makes sense. Cargo wagon is movable but the steel chest is immobilized.
Now, fluid wagon vs storage tank... I think you have already known what I want to say here:
Size: 2x6 vs 3x3
Capacity: 75k vs 25k
The size of a fluid wagon is only 133.33% of that of a storage tank. But it can store 300% fluid of a storage tank.
Efficiency = (75 / (2x6)) / (25 / (3x3)) = 225% !!
If we only want 6.944% efficiency in fluid wagon, it should only have 2.31k fluid capacity instead of 75k.
I laughed to myself when I first saw this number.
Tell me if I did it wrong.
Otherwise, what we need is not just reducing the capacity of each barrel by half...
Say, if we want a cargo wagon can also only hold 2.31k fluid using barrels.
A cargo wagon = 400 barrels
2.31k / 400 = 5.775
So each barrel should only hold 5.775 unit of fluid instead of 250....
I won't make a mod that goes this far. But still, 225% vs 6.944% sounds too much for me.
And I want to say... maybe the problem is not pipe or storage tank, but the fluid wagon and barrel?
Edit: Optera reminded that we can actually store fluid in steel chest using barrels! Let's look at the efficiency.
Steel chest vs Storage tank
Size: 1x1 vs 3x3
Capacity: 48x10x250=120k vs 25k
Efficiency = (120 / (1x1)) / (25 / (3x3)) = 4320%
I would let you decide whether it is a balancing issue or not.
