[PHYSICS] Fluid mechanics

[Esunisen]

Hi all,

Just few ideas for future implementations:

- Different viscosity for different fluids (not sure if implemented or possible)

- Communicating vessels

This: 

should be like this: https://en.wikipedia.org/wiki/Communicating_vessels. Also, the gas bubble trapped on the left should be able to escape to the right and the one in the middle should spread in both directions.

- Siphon: https://en.wikipedia.org/wiki/Siphon

- Restricting mesh tile, adjustable by duplicant like valves.

- Remote pumps with intake pipe and vent (grate ?) working as an input.

- Something that could block gases but not liquids.

- CO2 on top of water should slowly add a layer of polluted water (or carbonated water, drinkable by duplicants) https://en.wikipedia.org/wiki/Carbonic_acid (needs proper balancing).

The fluid dynamics in ONI are definitely strange, especially if you aren't used to them.

We already have this to a certain extent.  It takes over ~300 grams of petroleum for it to flow, but water only needs over ~30 g.

Liquids actually do attempt to do this.  They just do it very slowly and not completely, but with that extreme, you should see that the water at the top tiles of the upper reservoir should be going down.

Liquids in ONI are extremely viscous.

Siphons would be cool, but siphons operate on pressure.  Pressure doesn't really exist in ONI, so siphons can't exist without a building or heavy physics redesign.

Another example of broken physics 

Gas "pressure" is the same on both sides, liquids didn't move at all in 200+ cycles

Look at the way the pwater is distributed in the pool and that might tell you something. pwater is "heavier" than water and wants to fall to the bottom. But there is little to no lateral movement of the pwater in the pool so it cannot distribute itself along the bottom. Mixed fluids tend to form "pockets" that do not change much over time.

Not revelant, it was pure water on the first screenshot.
