If it helps, the output from one valve from a Xycraft tank powered by an autarchic gate can provide enough water for two engines running at max temperature, without using golden pipe. Allows for a more compact set up.

Couple of things I noticed through trial and error... well more like trial and error... error... and more error

I don't trust XY tanks pumping water, I had a couple or explosions, maybe I messed something up but the supply was XY water to tank and pumped to engines and was stable when I logged off!

Theory says 4 engines to 1 AQ but I went 3 as the setup was cleaner and I was already 20 engines down due to explosions!

Here is my biomass to combustion engine setup before I reached UU matter and needed constant power. 1 AQ with water either side (not front and back, no idea why someone thought that was true!) and liquiducts up to engines from underneath

They have a problem with that balancing crap through valves with multiple, adjacent tanks. i.e. You cannot precisely control the flow in/out.

Continuous outflow shouldn't be an issue as so long as you have ADEQUATE outflow for combustion engines.

Here there are two levels, the top level is hidden above the stone brick layer. 160 combustion engines feed off 80 values from two 5x10x4 xycraft water tanks. No issues:

I too have noticed that the theoretical doesn't match the actual. Luckily I've been nearby when my engines have overheated and have been able to turn them off in time before any exploded.

My setup was one AA to 4 Combustion, with a single water connection per engine using liquiducts. When all 4 reach max temp, the problems begin. I thought it might be me going too far away from this build, so I threw in a chunkloader...which did absolutely nothing. I don't have room right now to run multiple water connections per engine, so I added another AA and things seem stable.

This is what I do:

Autachic OR iron gate on wooden waterproof pipe attached to tank set to: If have liquid, pulse energy OR if have liquid, send red signal.

Then all the combustion engines are activated by a gate that has: If red signal, send redstone pulse. This way if my water runs out for some reason or the tank is damaged, all engines turn off immediately.

No idea if im doing this wrong. But im using 2x accumolators on one engine cause i have seen that one isnt enough when the engine gets hot. Everytime i leave the area loaded with a chunkloader and coming back after an hour the engine have exploded. Im using fuel as main source and liquiduct pipes ofc. Do someone else also have this issue? Any idea how to solve this?

Off the top of my head...

What is the engine connected to and how [I assume engine is constantly running, given your description]? Direct machine connection will cause engine to explode if engine output isn't absorbed/used quickly enough. Same goes for BC conductive piping, depending on what version of FTB/whatever modpack you're using. I remember reading there was an early version [1.4x ?] where the connection was lossy, so served as a power sink and prevented explosions thru accumulated power, due this was patched out around 1.4.5?

Best to use TE's redstone conduit and/or an energy cell of you have them in your pack. If you don't, you need to tell the engine(s) to shut off if they're accumulating power.

Remember an unpowerd Liquiduct can only accept 100mB and a powered one 150mB per connection, more liquiducts per AA will solve this bottle neck. BC pipes will accept whatever is pushed into them up to flow limit...

EDIT:- Nvm just read that an AA only produces 25mB/t so input limitation of liquiducts not an issue

I used 4 combustion to power up a quarry. It worked with same setup on the refinerys, but when i made it on the quarry they explode.

3 AFAIK. It can't be more than that because I blew my base up with 5 running on 1 AC
*remembers my base is running on a ratio of ONE AC to TEN combustion engines and theres a world weight right next to them and I haven't played it in a week* well my base is a goner...

Tbh Aqueous Accumulators are so cheap to make IMO, that I prefer to just make a ton of them. After all with combustion engines the problem seems to be a peak usage issue(Several engines needing whole buckets of water at the same time).
So last time I was using Combustion engines I made this setup(still using it for water since its so easy/cheap to set up):
tQESKaH.png

24 AAs in a sphere setup with an Ender tank in the middle. The tanks are cheap to make and doesn't seem to have any internal throughput limit(only the pipes/ducts connecting it have limits). Also this way I can deliver the water directly to where I want it, without any bandwidth problems of running pipes/ducts. And if you have need for more water, just make another cluster and link to the same Endertank.

Still I set up the engines with Gates detecting heat level and water supply to cut off engines should there be a problem with any. As a consequence I have never had an engine blow up.

WHAT IS THAT GLORIOUS TEXTURE PACK YOU GOT THERE

That is a nice way to cluster AAs. Do you know if 4xAA can saturate a gold pipe? They look empty so I guess they're keeping up with the AAs and delivering the water as fast as they take it in?

Ehm I have no idea tbh. You probably don't need gold pipes. They are in fact in my picture all full, since the setup can produce so much water at the time, and I in this build only really use it for farms/carpenters etc.

EDIT: Found these sources:
http://feed-the-beast.wikia.com/wiki/Aqueous_Accumulator
http://feed-the-beast.wikia.com/wiki/Golden_Waterproof_Pipe
According to this the AAs can produce roughly 25mB/t while a golden pipe is limited to 40mB/t. So it seems that the golden pipes are in fact a serious bottleneck in the system since 2 AAs will max out each pipe. Therefore I would reccomend using liquiducts that have a capacity of 100mB/t according to http://feed-the-beast.wikia.com/wiki/Liquiduct
