### Fluids, Pipes and Pumps

Posted:

**Tue May 02, 2017 12:56 pm**Hi everyone,

I just tested pumping water from one tank to another and count the ticks it takes with combinators and stuff.

If I use one pump connecting both tanks directly, the combinator reads 181 ticks,

so I'd say the pump can theoretically transfer 25k of fluid in ~3 seconds which means 138.12/tick or 8287.29/s (The tooltip says 200 pumping speed, which apparently means per tick, but I guess the in-/outputs can't keep up)

Then I used one pump with a pipe at the input...

...and then 2 pumps:

I tried this with 0, 1, 2 and 4 pipes (pipe-to-ground counts still as 2 normal pipes[tested]) and later with more.

Summary:

The results for one pump factor the tank in, which seems to count as something between 2-3 pipes.

When i used 15 pipes and one tank it took 1246 ticks (1203.85 fluid/s), so there it was ~3 pipes, but i haven't tested with different fill levels.

Since the pumps aren't the bottleneck anymore, it makes no sense to use pumps parallel now:

This setup takes 618 ticks to fill the tank, but if i remove the upper and lower pump, it takes 642 ticks, so it's really not worth it.

It looks like the sweet spot is 18 pipes between pumps for 1200 fluid/s (which the offshore pump can produce), so 18 pipes-to-ground would get you 99 tiles far.

I believe the results might be off by 1 or 2 ticks because it doesn't stop counting exactly on the tick when the tank gets full.If I use one pump connecting both tanks directly, the combinator reads 181 ticks,
