Guide to Atmospherics: Difference between revisions

Nitryl (formerly Brown Gas) speeds you up - pretty good until the acid eats your lungs. Generally produced only as a precursor to stimulum, or when somebody's pet star gets loose and starts turning the station into its burning core.

===[[File:Tritium.png]]Tritium===

{{anchor|Tritium}}

Freon is made by combining a minimum of 40 moles Plasma, 20 moles CO2, and 20 moles BZ in a endothermic reaction at temperatures above 473.15 K. The consumption ratio for the reaction is 6 Plasma : 3 CO2 : 1 BZ. Higher heat improves the rate of reaction.

Hot ice is a solid byproduct of the cooled Freon+O₂ reaction at 120-160K. Can be sold to cargo at a high price. It holds a great amount of power inside. Can be ground to produce 25 units of Hot Ice Slush.  

===[[File:Hexane.png]]Hexane===

Hexane is a very dangerous gas that makes you hallucinate, gives you brain damage (33% chance to do 5 damage every time you breathe it in until you hit 150 damage), prevents you from using changeling chat, gives you a slow down and makes you immune to radiation.

==The Atmos Devices==

'''This will be a section detailing the overall function, and some specifics, of the various pipes, pumps, and other devices. Some details will be missed, but it will provide a basis. The first instance of a device running into a unique mechanic will be explained in further length.'''

===[[File:Dvalve.webp|frameless]]Digital Valve===

A valve that opens when clicked, and connects the two pipenets it separates when doing so. A pipenet is any collection of normal pipes connected together, including some sub types. Counter to pumps, it experiences no delay in its gas transfer. It essentially acts as a pipe, which, as all pipes, transfers gas instantly to all connected pipes. Has 200L of volume on one side, and 200L on the other end. This can be operated by both carbon mobs such as humans, excluding xenomorphs, and silicons.

An activatable valve that lets gas pass through if the pressure on the input side is higher than the set pressure. Good for situations where you need to keep pressure under a certain level.  

Acts identically to a Digital Valve, however, the manual valve does not allow silicons to operate it. Good for when you do not want the AI interfering with atmos.

===[[File:Ppump.png|frameless]]Pressure Pump===

An oddball case. Like all pumps, it separates connected pipenets if there is nothing else connecting them. Has a maximum pressure of 4500 kPa. All pumps work by pumping the contents within them to the other side, which is 200L on one side, and 200L on the other. Any pump can not pump gas that is not actually in it, which means that very large connected pipenets will have lower pump speeds. Pressure pumps work by gradually building up to its set pressure per tick. Because of this, pressure pumps slow down when approaching their target pressure, and will not quite match their pressure after a very long time, but will get very close.

The volume pump is similar to the pressure pump, but operates differently. It has a pressure limit of 9000 kPa. However, this limit only kicks in when the output pipenet is currently over 9000 kPa. The pump will work if the output pipenet is below 9000 kPa, even if the resulting pressure of this action would be way higher than 9000 kPa. Counter to the pressure pump, this pump works on a L/s basis. This has a 2x200L volume as well, so you pick how much of the volume in the pump is actually pumped to the other side by changing the number. Because its max speed is 200 L/s, it will always outpace and outpressure the pressure pump. Can be overclocked using a multitool, which will cause its pressure limit to be dependent on the input pipenet, which will tend to make the maximum output pressure higher. However, this will cause 10% of gas running through it to spill.

===[[File:Pgate.webp|frameless]]Passive Gate===

These are a combination of pumps and valves. They work up to their set pressure, with a maximum of 4500 kPa. These can never do more than equalise the two connected pipenets, just as valves do. However, they only work one way, rather than mixing the gas between the two pipenets perfectly as valves do. Very rarely used as the pressure valve tends to fill most of its use cases, but can be used in situations where one needs pressure control for a pipenet that needs to remain between two values, the upper bound being the set pressure and the lower bound being the output pipenet pressure, such as a BZ reactor.

A gate that only lets gas through when they are on one side of the set temperature threshold (either greater, or lower). The mode can be changed by using a multitool on the device. Excellent for precise thermal regulation and failsafes for the SM engine.

===[[File:Vent.webp|frameless]]Unary Vent===

===[[File:Atmosfilter.png|frameless]]Filter===

The filter is the first device that connects 3 pipenets. It can be set to a single gas, and it will dump this gas to the side it is pointing in. All gas that is not selected will continue straight forward, as the arrow is pointing in a single line. When set to Nothing, it will allow all gas through the straight path. The filter works in L/s, and as such does not experience pressure related slowdowns, however, it has a pressure maximum of 4500 kPa. When EITHER OUTPUT SIDE is 4500 kPa or above, the filter will not function, not allowing any gas to pas. That is, both in a straight line and on its offshoot, the pressure must be less than 4500 kPa.

The mixer also requires 3 connections to function, as the filter does. The mixer will mix the two incoming gases using the ratio the user inputs, starts off at 50/50. Node 1 is the input in a straight line with the ouput, Node 2 is the offshoot compared to the output. Both inputs need to have gas in them to function unless a side with gas in it is set to 100%, in which case it will function and purely let that side through. Is pressure based, with the associated properties. Also has a pressure maximum of 4500 kPa. The mixing is influenced by temperature following the ideal gas law. When one of the input sides is hotter compared to the other input, it will let less of this side's gas through, mol-wise. This will give you scuffed ratios if you do not equalise temperatures, if you need the precision, make sure they're equal.

'''Fire''': An effect caused by burning plasma, fire comes in two different forms of hotspot. It causes massive burn damage, and a strong fire will not be stopped by standard firesuits. Plumbing N2 into a room might work, but heavy firefighting is not the point of this section. Fire will ignite any form of combustibles in near tiles. Sufficiently hot fires use less oxygen as they rise in temperature. This is due to the fact that fires remove X plasma and X*(1.4-Y, Y< or = 1) oxygen. X CO2 is produced. Ideal Burnmix is: 10x more O2 than plasma, and with as high a temperature as can achieve.

==Atmospherics Layout==

{| class="wikitable"

|[[File:Atmos_simplified.png|thumb|499px|"Simplified" picture of the Atmospherics pipe system. Yellow circles represent filters and the lightbrown circle represents the mixer. ]]

|}

Atmospherics is pretty simple, but the pipe layout makes it slightly confusing for the untrained eye. There are 4 major pipe "loops":

*The '''<span style="color:blue">dark blue pipe loop</span>''' is the distribution loop. It sends air to all the vents on the station for the crew to breathe.

<br>

*The '''<span style="color:cyan">cyan air mix pipe loop</span>''', which is specialized to mix and provide the air mix to the distribution loop, and is used to fill air pumps outside the front door of Atmospherics.

<br>

*The '''<span style="color:yellow">yellow</span> pipe loop''', internal to Atmospherics, which is used for custom gas mixes that can be fed into the canister charging station in the middle of atmospherics, or fed into the mixing tank.

To understand how the breatheable air mix is mixed, try following these steps and looking at the map at the same time, it starts on the south end of Atmospherics, like so:

#They are mixed in the air tank ('''Air''') to a 1/5 mix of O2 and N2.

#The breathable gas is then pumped through the '''<span style="color:cyan">cyan loop</span>''' to the north of Atmospherics.

#Scientist Bill messes up and fills the [[Toxins Lab]] with plasma but fortunately manages to evacuate the room safely.

#The plasma arrives to the Waste In -loop (the red pipe loop) at Atmos. It travels south through the pipes, its first stop being the N2 Filter.

#If there was any Nitrogen in the waste gas, it would get filtered out here, and the rest of the gas continues its journey through the waste loop, same thing happening at every filter.

#Here the plasma gets extracted from the waste gas and pushed into the big plasma tank-room outside the windows.

#The plasma stays in the room until someone decides to pump it out.

*'''For the love of Nanotrasen, at least do this:'''

::'''+ Quick toxin filtering:''' In case of a toxin leak, waste gas will be sucked out quickly (if the area's air alarms are set to filter out all the toxins, that is, by default they are NOT filtering anything).

::'''- Space wind:''' In case of a breach, until the hole is fixed, you'll probably spend a small while fighting against the huge air current, a.k.a. "space wind", if you don't switch the vents off during the repair. This is mostly just annoying.

Done correctly, Atmosia should be pumping good air just faster than it's lost, and draining bad air away as fast as the traitors can set it on fire or alternatively draining good air away as fast as a malf AI can siphon it. You can go kick back in the bar like a boss and wait for the inevitable minor station damage and cries of "Call the shuttle!" on the radio from folks who don't even know it ain't a big deal.

*First and by far most important: make sure pipes don't get broken and if they do, fix them.

*Go around swiping your ID on [[Air Alarm]]s, setting the operating mode to contaminated, and then re-swiping to lock it. You can ask the AI to do this as well, and probably should.

*Make extremely extended oxygen tanks for internals use (instructions below).

# Go to the red lockers, get a hard hat, gas mask and everything else that might be of use. Remember that you need both a fire suit and a hard hat to be resistant to weak fires. One will be useless without the other.

*On a basic view, a 16 kPa minimum O2 requirement in internals. Pure O2 is theoretically toxic in real life, but has no representation for this in code, and takes a while to be really dangerous anyway (they use it to treat certain diseases, for example), and thus using a tank filled with air for internals is fairly inefficient.

*Cold O2 has more moles per kPa, and because people breathe in moles, and filling tanks usefully for internals are largely capped by the 1000 kPa release pressure, means cooling your O2 before using it in internals is important! Cooled down O2, such as from a freezer-ed canister, is the most efficient way to set up internals. Cooling it below 264 K will result in icicles inside in your lungs, though!

*An emergency oxygen tank with normal settings lasts for about 12 minutes. Same tank, but with optimized gas temperature and output settings reduced, lasts about 50 minutes. If you don't have resources to get cooled O2 right now, set your output pressure to 16 kPa, it will give you 31 % more time to breathe.

===Fun Projects===

*No one uses the ports outside of the 'refilling' station, but that doesn't mean that functionality can't be added onto them!

*Don't count out the grated window areas, they can be a great (har har) way to utilize the vacuum of space without an EVA suit.

*Speaking of EVA suits, your engineering buddies can potentially help you with anything you might want to do in space, be it adding or modifying pipes. Watch the hilarity as that incompetent engineer fumbles with the huge crate of pipes he dragged out into space for you!

*The main cargo area inside Cargo has a laughably small number of vents, and how many times have those dumb dumbs sent the shuttle off while the doors are open?

*The brigs distribution system is set up to be potentially independent of the rest of the station's distribution loop, maybe other places can be set up like this as well?

*Any gas at pressure over 1000 kPa will cause you to start suffocating as in a vacuum. You can just use internals, though.

*Any gas can displace O2, and less than ''16'' (also useful for optimizing internals) kPa of oxygen starts the Oxyloss. CO2 can be removed with the scrubbers, but to get rid of N2 simply apply some way of removing gas from the air and adding O2. My personal favorite is 2 air pumps, 3 connectors and an Air Filter and a canister: 1 pump draws in, goes through the connection and filters N2 into the canister, and the rest to the other pump, which expels it. Can also be used for N2O which is only sluggishly scrubbed otherwise.

{{anchor|Atmos Resin}}

The Backpack Firefighter Tank[[File:waterbackpack atmos.png]] can switch modes to launch transparent ATMOS resin instead of extinguisher. This resin has the following effects:

*Repairs hull breaches similarly to [[Guide_to_chemistry#Smart Metal Foam|Metal Foam]].

*Normalises air temperature to room temperature (20°C or 293.15K).

*Removes slipperiness from floors (from water etc).

*Your holobarriers let people walk through, yet block gases. Very useful for cleaning up Plasma spills, fixing hull breaches and keeping fires in check.

*Air Filters and H/E allow you to expose gases to the heat of fires (or their CO2 product) but keep/make them pure, allowing for hot N2O or similar.

*Using a small starter flame/heater you can have in pipe combustion.

*Canister bombs are heated Plasma in a canister, with an O2 tank placed in the canister, and then open the valve between them. You will also need to run very, very fast.

*Gas pumps are for precise pressure control, volumetric pumps are for really fast pumping, and passive gates are for having 'one way' manual valves.

* If about to unwrench a pipe known to contain deadly gas, use a holobarrier on the tile first, then unwrench, this will keep the gases isolated to that specific turf. You can then bring your portable gas scrubber to the holobarrier'd tile and clean it up much, much faster and much safer than if you had unwrenched it without a holobarrier in the first place.

*BZ deals damage based on the pressure, not percentage of the air that is being breathed in. This means that hot BZ is more effective than regular air-temperature BZ. This just might give you a bit of an edge when plasmaflooding, or if you want to use an invisible deathgas flamethrower.

*Using a pump of any kind after a scrubber is highly redundant and drastically lowers the effectiveness of the scrubber as it separates the pipenets and cuts off volume. The SM and the incinerator's scrubbers can be massively improved by simply replacing the pump with a straight pipe.

'''NOTE: The following guide covers the bare essentials of fusionv6 and should be enough for you to get started with your first few fusion canisters. The more complex bits regarding the kicked rotor, open-tile fusion and SM utilization will be provided at a later date, the essentials are being rushed out so that there's at least something there to work with.'''

===The fluff===

There are 4 requirements to plasmic fusion: Lots of plasma, lots of CO2, lots of tritium and lots of heat - the result is a LOT more heat (by several orders of magnitude), a lot less of your starting gases and enough rads to make the SM feel thoroughly inadequate. The radiation itself, while deadly enough to kill when a subject experiences 30 seconds of exposure, or is hit by even a single cluster of hyperenergetic decay particles, is a tiny threat compared to the ravaging heat of a newborn star shackled by the confines of your canister, begging to be set free and set the station ablaze. A containment failure of a fusion canister will result in severe consequences and definitely something the gods will notice, so be careful when attempting it. Also, atmos techs are a very closely-knit community and most techs who learned fusion were taught or in some way assisted by a tech who knew it beforehand, if you find a willing tech, ask him to teach you as this is an extremely dangerous and autistic activity.

Disclaimers and safety pronouncements, aside, let's get to what you actually need when doing fusion. There are different recipes for achieving fusion, but the most well-tested, consistent and widely used recipe is the '''6 plasma : 2 CO2: 1 Tritium''' recipe popularized by the first atmosians who birthed stars. One such canister should have 6000 moles of plasma, 2000 moles of CO2 and 1000 moles of tritium - the amount does not need to be exact and can vary by as much as 10% in ratio, as long as the 3:1 ratio between plasma and CO2 is preserved. Technically, a canister can fuse as long as it has a '''minimum of 250 moles of plasma, 250 moles of CO2 and 1 mole of trit''', but the results are not particularly useful or exciting. Any amount of plasma and CO2 are okay, provided that they follow the ratio, and the fusion reaction will continue until it has less than 250 moles of CO2 or plasma, or it runs out of tritium. Once your canister is nicely made, heat it up to 10.000°K via heat pipe exposure over an actively burning tritium chamber (the incinerator has all the necessary equipment, and is probably where you made your tritium to begin with), then '''please unwrench''' it when it hits the 10.000°K mark.  

Once your canister is nice, hot, finished and ready; and you aren't a dying radioactive meatbag clinging desperately to his last vestiges of life, you may proceed to use the fusion canister for generating hypernoblium, or maybe nitryl and stimulum, in large batches, for personal consumption or shipping to cargo. A good canister of hypernoblium is easily worth half a million cargo credits, skilled atmos techs consistently make ones worth upwards of several million credits. Alternatively, you can use the fusion canister as a traitor and unleash your newborn star onto the station, killing anything and everything inside as it is engulfed in an expanding cloud of gas hotter than the heart of many suns.  

If you are exposed to radiation without the appropriate insulation or '''hit by a particle''', do not panic, take your charcoal/antitox/anti-rad pills and you should be able to tank the toxin damage from the rads and keep some mutadone with you if you mutate (you will). If not in a rad suit, do not immediately run to medical because you will contaminate it and get '''a lot of people killed.''' Instead, scream over radio that you need radiation treatment in the form of more anti-tox or charcoal dropped off in maintenance for you to grab and use. Do not let doctors or paramedics '''get near you''', you'll only get them killed unless they're rad immune already. If hit by three of these, hope that you have enough medicine to keep you alive, as the next 10 to 20 minutes will be hell for you as your radiation damage accumulates and you mutate into a filthy subhuman. If hit by 5 or more of these, even if in a radsuit, isolate yourself and suffer a ''colorful'' death.

===I would like to understand the mathematical background of fusion dynamics and/or have severe autism===

*You can harness the radiation produced from fusion to produce power using rad collectors. Earn your keep as a member of engineering. Or just use it for pluoxium production.

*The higher the temperature, the prettier the fire. See if you can get the prettiest color fire.

Or: How to get the AI lynched; How to call the shuttle as Atmos Tech, step-by-step:

#Set pumps to the distribution loop to maximum pressure output (4500 kPa).

#Open valve from custom mix chamber.

#Wait for vents to slowly kick out your deathgas mix as regular atmos drains out through the inevitable hull breaches (alternatively turn off pressure checks on air alarms' vents to speed things up).

An extremely fast method that involves a clever use of the waste system is the following:

#Find a place with a waste pipe next to a distro pipe, then configure them so that they can be united later.

#Open the valves for your deathgas mixture of choice, the waste piping should now begin to fill with your gases.

#Set as many air alarms as you can to have every vent at Internal 0.

#When ready, go back to your distro/waste pipe spot and unite them.
