How can I split "liquid" evenly into two pipes?

I have tried:

1. with pumps 2. without pumps In both configurations, almost all the "liquid" goes into only one pipe.

Impossible.

The only solution is to make one plant stop after a while so the other plant can use the liquid.

Or produce fast enough to support both plants.

This is about the same problem as here: https://forums.factorio.com/forum/vie ... f=8&t=4814

I think the algorithm has to decide into which network the fluid/power goes.

since both chemical plants produce solids, you can control how much liquid goes to each by limiting how much product material is produced by each.

for the plastic plant, use a smart inserter on circuit 1, followed by a smart chest on circuit 1, followed by a smart inserter on circuit 2.
For the Sulfur plant, use a smart inserter on circuit 2 followed by a smart chest on circuit 2 followed by a smart inserter on circuit 1.

The first smart inserter on both sides only operates when the smart chest next to it is empty. The last smart inserter on both sides, only operates when the other sides smart chest has one item in it. Both items should be delivered at the same time, but in the worst case they should alternate deliveries.

If you wanted uneven production you'd need to create a switch that checks the amount in both chests and then passes an item to "switch" on the final smart inserter and then reset.

Is there a problem with using wood planks as the fuel?
I would recommend using the shortest burning fuel possible, so that the distribution is smoother, instead of being pulsed.

Quite the contraption , but nice work.

i figured out if you pipe into two tanks it evens out

Only if the entire length of pipe leading from the two tanks is the same. (e.g. 20 tiles of pipe to a chem plant from one tank, 20 on the other.)
I suppose the two tanks idea would also work if you exclusively filled the tanks to full, and then stopped the input and started the output.

I imagine the use cases for forcing a split in a liquid would be cases where there was an uneven use rate. (e.g. plastics vs sulfuric acid)

you can if you do 2 thinks
1) on the pick "2. without pumps" add 1 pumps just out side the tanks and befor you split the pipe.
2) let the pipes between the pump and chemical plants full up and make more Petroleum Gas than thay ned.

i have do this for 10 chemical plants if you can keep all the inputs full i can/do use all 10 at the some time

I guess you could use any fuel, but where do you want to get a (semi-)constant flow of wood planks from? I always use coal for my power backup, because it has the lowest energy content of the fuels I can supply to the storage almost continuously, making it almost never run out unexpectedly.

Large amounts of deconstruction designation of forests.
Would be a problem if you started in the middle of a large desert or wasteland area, but otherwise, thousands of wood for a screen-sized chunk of forest.
I don't see extending a logistic network as being too off-putting if you've got the time to be working on a setup like this. (resource-wise, of course.)
