Submarine Help

[ghettodexter]

Ballast tank example anyone? Not sure how to build a submarine... I made one with a tank that has smaller tanks inside filled with air to 32psi, pump water into large tanks and sub sinks... open air valve to purge water back out but it never pressur goes down in air tanks but sub never surfaces... Am I designing this too realisitc?

mnjersey has a sub tutorial on his youtube channel. I strongly suggest you watch it. I even has an auto deph guide!

you are just creating A vacuum by pumping out water. Unless they add oxygen generators you will need to pitch up using rudders and go forward

When generating vacum, you will surface more rapidly. Vacum is lighter than air.

I think out from the info that the sub is too heavy and/or the tanks are too small so it does not affect the buoyancy enough for it to surface. Or just lots of bugs

THanks guys I will look into your suggestions... as far as weight its a single seater with no accessories... just enough to make a functional submersible.

if the tanks are large enough to make it float at spawning then empty they should be large enough to brign it back to the surface. Inside each tank are smaller tanks filled with air pressure when I open them the large tanks are not effected only reason i made the purge tanks are because the water wont pump out my large tanks but will pump out of the cab (weird I know the piping is correct)... ugh im stuck...

[Johannes]

Ok. As I understand you are using the default tanks (small med amd big tanks). These wont react the same way as a custom tank. Use a sealed space and build in a fluid intake. This will work I assure you.

MrNjersey... lol couldn't find mnjersey

[ghettodexter]

ANd no im using custom tanks with default small pressurized tanks inside. the small tanks are used just for air pressure (only exists inside pipes and engines but vanishes in enclosed spaces or doesnt effect physics the way it should e.i. push water out of the same volume)...

[ghettodexter]

Sorry your idea of physics is wrong though... Vaccum is lighter than air becuase its the absence of air... therefore a vaccum will sink more rapidly due to the fact there is no air to float on the water. BECAUSE SCIENCE

[ghettodexter]

Like I said I think im over thinking the physics of the game or they are too unreal for me to process how they should work... fill with water... where does the air go and why no increase in tank pressure? so I add airventing system, like a real sub you have limited air supply and must recharge ballast tanks with high pressure (small tanks) and to sink you fill large tanks with water until the weight of the water overcomes the lift of the air inside the same volume as its not the ammount of air the lifts but its volume or how big a space it takes up X its psi (physics) so if you squeeze the air in your ballast tanks down by filling with water you will sink (real life) then use stored pressure to push air back out (no pumps needed) unless under high pressure at far depths below the sea (reason I have 4 32 psi tanks and two pumps). I know it sounds over-kill but everything I make is yet its compact as hell and SHOULD work... even for this game its design is like the basic one in that youtube video you told me to check out... but with more features. Thinking of uploading to the workshop so you can see what im saying

Ok, so a bit of science is required here.
Air has mass. 1.225 kg/m3.
Water has around 997kg/m3. Now that means that air is a lot lighter than water. A cubic meter of air comsealed in a massless box(just hypothetical) under water will rise rapidly simply because it is lighter than the water.
Vaccum has a dendity of 0 km/m3.
That means that it will float much better. Because it will implode to nothing when released in the air wee have to seal it. For a vaccumchamber we need a strong tank. That is rather heavy so it is depending on the size of it it to float.
In stormworks there is no real physics. Nor do you meed a strond container for vaccum. But as a fact. Vacum sealed in a box will float better than air inside of it. It may eaven fly into the air.

Yeah this is why physics is fun, It's hard to "grasp" A true vaccum is the absence of air its weightless because its nothing, a true vaccum under water will only have the weight of the object holding the vaccum competing with the water, but no it will not float unless the object holding it had buoyancy

[ghettodexter]

IDK man... this would be a good bet... two perfect spheres one under extreme vaccum one filled with air... who will float and who will just crush under the pressure of the outside environment?

[Johannes]

Yes, its quite fun with physics. But like I said "For a vacuum chamber we need a strong tank. That is rather heavy so it is depending on the size of it it to float." It will however float better than the same tank with just air. And a sphere with air will also implode under the extreme pressure.
Submarines however stores compressed air that from the ballast tanks so it can reuse it to force the water out to surface. So for practical use we dont use vacuum because like you said it will implode. Not in stormworks though.

Anyway when making a sub, use custom tank and pump water in and out. No need to store any compressed air, and when pumping out the water it will be replaced with air. I'm not completely sure if they have changed it the last few days, but all you need is a custom tank, 1-2 pumps and fluid connector.

I have a working sub on those principles. It has not been updated for quite a while so it floats a bit too much, but with the elevators it will submerge.
I just tested it and it seams that it is still working, but needs a bit more ballast.

DUD you're awesome thanks.
