whats with the plumbing?


Recommended Posts

Hi, i work at a building hydraulic consulting company. and why is all the plumbing upside down. the drainage should be gravity fed, and why no  floor waste/ sumps/ strip drains/ rain water outlets? and what about drain vents. why must all the plumbing use the pumps, why not pump water above the base the a tank then gravity fed the system?  how about a drainage tile that feds in to the pipes

At a guess?  Simplification.  The outbound pumps, such as the lavatories and what not, are kind of but not really what you're thinking of.  The same could be said of the atmospheric lava lamp, why food can grow in 10 days but needs a lake to feed it, and why you can pressure control a room with a little bit of liquid in a corner.

All of that stuff could all be intricate and perhaps interesting, but each piece of the puzzle that gets added in can move it in strange ways.

can dups walk on the roof? .... no then heavy dense fluids will push lighter fluids out of the way, and move to the center of mass. ... do you have something against getting pressure relief valves, moving water down in pipes with out uses of power, condensate valves to drain vent pipes, and a tile that collects liquids that fall/land on it. and it's a standard practice to run the water supply in the ceiling.

 

and how about a air flow fan just to get the air moving, get heat and pressure spread faster.

and maybe a in line booster pumps

or water wheels for power.

Good point. I've always wondered why the sink/bathroom inputs are on the bottom and outputs on the top. Should be the other way around.

All of that would require reworking the game engine. Simulating those things wouldn't be simple additions. For example adding a fan would mean gases would need to have velocity which right now isn't something tiles even track. 

If such fan were added, I would imagine it would work like wheezeworts do now, taking gas from one tile and moving it to another. Don't need velocity if a pressure differential does the work instead.

That would actually be a simple addition. 3x2 tile vertical 'wheezewort' fan, no cooling, just moving gas around.

It's only a good argument if developers are striving for realism BUT first of all they don't(as far as i understand) and second it's impossible because simulating real world would take huge processing powers and our computers and not all that allmighty. Also the main goal of game is to be fun and maybe systems that are heavily realistic are not that fun or game can't work like that? That can also be the case.

The problem would be that a pressure differential isn't the same as a breeze. Note how a wheezewort doesn't actually create an updraft that continues upward for several tiles; it simply creates one tile with more gas that then immediately diffuses back down in all direction. Outside of the two tiles, there is really no net movement all you have done is change what the density distribution looks like.

Ah ha ha ha. Someone's never created a wheezewort zero power pump, I see. Try putting walls around that output side and see what happens. Or enclose the output end in a room. A 3x2 pump size would enable doing just that, easily.

e. I've created a 12kg pressure differential with a staircase of 4 wheezeworts using seed planting in natural tiles.

e2. just a quick sandbox test. pressure differential in the room is holding steady at 1.5kg over the outside (3.5kg vs 2kg). Now imagine a dedicated 'Fan' thing rather than the plant.

e3. dropped the outside pressure to ~250g, inside is now up to 4.5kg. huh. Fan using pressure differential seems quite viable.

e4. Have the save if you want to play around with it.

That is only because you have sealed off each side so the air so it can't circulate. You have created a pump not a fan, you can achieve the same effect with a pump and a vent directly after it.

 

Heres an example of why this doesn't really work as a fan like you would want it to.

We start with a room filled with natural gas with a strip of slimelung and a pump that moves air from one side of the pump to the other. I leave the room to sit for three minutes on triple speed and unsurprisingly the  slimelung doesn't move. Now let us see what happens when we turn the pump on and wait another three minutes.

Nothing, the gas is still not circulating. Yes there is a high-pressure area to the left of the pump but it doesn't actually cause any movement in the air. All it does is change what the equilibrium of the room looks like. The only gas movement that ever occurs is that between the input and output of the pump and a very small bubble around it. If I move the slimelung directly onto the pump it creates a small bubble of slimelung around the pump but then it just stabilizes and the slimelung never leaves the bubble which stays the same size. Without gases retaining velocity the most you can do is move gases from one tile to another which the pump already does best. With the current system if you want to cause a breeze you need something at opposing ends of a corridor, with one end dropping pressure and the other raising it with the breeze flowing between the two ends.

Ever put a box fan in a window? That's essentially how I would want to use this 'fan'. Not in an open room, the pressure stuff won't work that way, but with dividers on each side to ensure it moves where I want it to. Basically a pump, pipe, wall, vent, but much easier to set up.

See the series of images below for examples. Imagine that the 3 wheezeworts are instead an arbitrary 3 wide by 2 high fan, of the design that could/should be added.

Before activation, 2kg of oxygen on one side, vacuum on the other.

After activation, .5 cycle later, 6.5kg per tile above, near vacuum below

Seems to work pretty good for me.

See, I think that in video games, you should always make things realistic, but not cumbersome-realistic. Having to connect fancy machines to all of your pipes would just be annoying, in my opinion. The way it now works is perfect for me.
