Water pumping broken?


Recommended Posts

Hi,

I'm at 150 cycles or so. And I am at the point to get some electrolyzers going. 

I have 2 pumps both pumping and dumping some water back into the reservoir (3 outlets) and then 1 in 4 bubble go to a valve which is set to 750g/s, that is connected to the electrolyzer. 

Now I saw some youtubers getting 1,25 kg of water per bubble in the pipeline. but both my loops have still 10KG of water going trough the pipes without splitting the water in half each time they pass an outlet. so i have 10KG going into the valve, and it keeps backing up my line.

Anyone have tips? or solutions? or is the water pumping pretty broken at this point? 

I cant seem to get a workaround going, without wasting massive amounts of precious water. already burnt about 30T of water in just 10 cycles or so.

Avoid going between water flows and pipes as much as possible. There is mass loss somewhere in the fluid handling.
Not much water loss once in pipes though, but there are a few quirks related to saving and loading.

If your electrolyzers aren't consuming water for any reason ... such as max gas pressure, or they are disabled, the valve is still letting water through at the rate you set.  This will continue until each unit of pipe is at max 10 kg pressure.  This doesn't change the rate at which the water in the pipes is consumed.

No its more that I want to deliver about 1,25 KG of water to the valve so it can break it down in to 750 per bubble.

But 10KG is still going into the valve, and keeps feeding it 10KG. The valve still breaks down to 750g/s x 12 bubbles. But when the water backsup soooooo much, I know I am loosing water in the process. I think I will leave ONI for 2 weeks until the next update. It's not so much fun when you consistently are loosing a resource to a bug. 

 

STILL LOVE THE GAME THOUGH!!! Great stuff KLEI keep it up.

Worth every penny already and it is not even ready.

Why would you assume you're losing water? The valve just trickles the contents of the packet behind it into the pipe ahead of it. Both pipes can hold the same amount and every partial packet that collides with each other will merge to fit the max space available.

In fact, using a valve reduces the amount of time your pump is operating, which reduces the fluid lost from the pump ignoring the contents that it pumped last tick when it shuts off.

Splitting fluid between branches does not reduce the mass, it just sends every other packet down each line.  Are you splitting the main pipe once and then one goes to the electrolyzer and the other gets split 3 times?  If so, it's only reducing the total volume in half.  If you split off the main line 3 times it will reduce the total volume by 1/2, then 1/4, then 1/8.  This means it gets 10kg every 8s, which is 1250 g/s.

I thought the same thing happened until I decided to close the pump and watch for how long the water travels in the pipe, and what I saw is there is no loss of water. I had around 10 pipes full of water and the valve/electrolyser took a long time to use them all at.

You "see" 10kg moving but it isn't really moving 10kg. It's only moving what it needs and pushes all the water up in the pipe at the same time, giving the illusion that 10kg is going in the valve.

And you can notice the pump pumping very scarcely, it pumps once after 10 bubbles moving, which means the pump is pumping the correct amount of water too.

While you have a point with the valve making it better, the bug still destroys plenty of water:

Well, (hopefully only) four days left till the fix, and counting...
