why is water specifically so hard to deal with?

[Lothos]

I mean seriously, I have no problem with every other fluid in the game aside from water. Is there some kind of unique in game viscosity to water that makes it such a pain in the ass to flow?

Present issue is moving water across the map by train and getting it to load/unload as easily as all the other fluids I am moving in the same manner. I've resorted to simply using a straight line of pumps from point to point as much as possible and even that has problems at times.

Do you have a screenshot as an example? And could you describe in more detail what your actual problem is?
Just as a side note: I don't have problems with water. At least none that I am aware of^^.

[Lothos]

oh, i have several spots i can choose. its an overall difference with how water flows in pipes compared to all other fluids.

I'd guess it is simply due to how much water you need, compared to other fluids.

All the fluids use the same mechanics, at low-throughput you will never notice the flow bottlenecks due to pipe junctions / loops & order of build placement / tick update.

There was a post on reddit by Rseding91 about possibly changing the fluid mechanincs, so pipe segments work similarly to belts / tracks, ie: one combined block with in/out totals. Seemed like a good idea to reduce the poor-flow oddities related to junctions & build / update order.

actually, the volume of crude and petroleum I move by train is more than triple the volume of water. Hell, even acid which I dismantle and move for mining uranium often flows a hell of alot better than water. It's always been this way too.

Pumps reset the flow speed to 1200/s, whereas the offshore pumps are more like 12000/s (if I remember correctly). The pumps may be restricting the flow.

How fast is the water flowing onto the train? I'd say the train should completely fill within ~21 seconds (25000 units of water per tank on the train, 1 pump / tank, 1200/s load speed), assuming that the storage tanks are all full when it pulls up

[KatherineOfSky]

@Yugatha, those rates changed in 0.15 -- pumps no longer restrict the flow of liquid.

[Yugatha]

Thanks @KatherineOfSky. I've just loaded Factorio, and can confirm that pumps also push through at 12,000/s, it's the offshore pumps that are only 1200/s

[Lothos]

the actual loading is fast once the water is in the tanks next to the track like all the other liquids. Going from the resevoir tanks to the loading ones takes longer. Much longer than other fluids with the same setup.

And the same when offloading.

[Lothos]

no

[Yugatha]

I've been playing with water and pumps and all that jazz for the last 25 minutes, and the only conclusion I've come to is that fluids be whack...

Playing with this setup

Tanks in the train take different amounts of time depending on whether a tank is separated by itself or connected to others. Separated tanks (regardless of whether it is the front or the back) are quicker at loading by about 10-15%

I guess, is the resevoir -> buffer taking too long, and causing the trains to wait a long time?

[KatherineOfSky]

It's inadvisable to connect directly to a tank -- those have some throughput issues. Try routing the pipes around the tanks and see if that improves flow. (Or possibly just directly connecting to the offshore pump?)

You have a lot of reservior tanks and I have no idea if thats good or bad. This is what I have for loading water into trains...

The times are as good as I can estimate with a watch in one hand and a beer in the other, but it takes about 11 seconds to load the train and about 18 seconds to top off the reservoir tanks to 100%. I did notice that the reservoir start filling very quickly, but as they reach...i dont know maybe 90% or so, the fill rates start to slow down a bit.

[Lothos]

i have alot of trains coming through the station though. Hence the big resevoir. The prefill tanks also let me fill a train in about 6 seconds.

all i'm saying is all things being equal if you take any other fluid against water and you'll see water does not flow as fast as everything else through standard pipes. And if you put any kind of moderate to extreme distance in there and you're borked.
