Atmospheric Science refers to the observation and processing of gases in enclosed spaces. [[Atmospheric Technician|Atmospheric Technicians]] are concerned with maintaining a safe atmosphere in the station by:
= The Basics of Atmos =
# Setting up the station's gas distribution system, or "distro," to supply the station with breathable air.
Atmos seems complicated on it's surface, but it's easier to understand once you learn the terms and how gases work.
# Using handheld gas analyzers and fixed air alarm systems to monitor levels of both safe and hazardous gases.
 
# Utilizing holofan projectors and inflatable walls to cordon off hull breaches or gas leaks.
== Pressure ==
# Moving and placing portable scrubbers to manually filter the air in case of escaped gases.
 
Pressure is measured in kPa (Kilopascals). A safe amount of kPa is 80-140 kPa. If kPa falls under or over that amount, most creatures will start to take barotrauma damage. Most atmos devices are set to 101.3 kPa.
Pressure rises as temperature rises, and lowers as temperature lowers.
Gases will always try to flow from higher pressure to lower pressure to create an equilibrium. It's important to be mindful of the pressure in a room or pipe before you open a door or unanchor a pipe.
Most atmospheric devices clog around 4500 kPa, some only clog at 9000 kPa, and some don't clog at all.
 
== Temperature ==
 
Temperature is measured in Celsius and Kelvin. A safe amount of temperature varies from species to species, the temperature a room should be is around 20°C (293.15K) as that's safe for all species.  
Heat and cold will always try to spread to create an equilibrium. Be mindful before you open a door or unanchor a pipe. Remember that space is naturally cold, so any spaced rooms will be very cold after you patch them up.  


= The Basics of Atmos =
== Mols ==
The premise of Atmospherics (or, Atmos) is simple: You want a station that is pressurized and with breathable air, absent of any toxins. The two primary gases used to accomplish that goal are Nitrogen (N2) and Oxygen (O2).
Oxygen is the breathable gas in air, and is respirated by [[Playable Species#Human|Humans]], [[Playable Species#Oni|Onis]], [[Playable Species#Felinid|Felinids]], [[Playable Species#Arachnid|Arachnids]], [[Playable Species#Moth|Moths]], [[Playable Species#Vulpkanin|Vulpkanins]], and [[Playable Species#Harpy|Harpies]] to form Carbon Dioxide (CO2) as a waste gas. Nitrogen, on the other hand, is respirated by [[Playable Species#Slime|Slimes]] and [[Playable Species#Vox|Voxes]] instead of Oxygen.


Pressure, measured in kPa, is determined by the amount of gas (in mols) in an area, and is directly related to temperature (in Kelvin or degrees Celsius); so as temperature goes up, so does the pressure. A safe pressure on the station is roughly around 80 to 140 kPa, and a safe temperature is around 20 degrees Celsius. The ideal environment for all species is 21% Oxygen and 79% Nitrogen at 101.325kPa and 20°C or 293.15K
The exact volume of gases is measured in mols. It is important to pay attention to the exact mols of gases, such as dealing with the TEG or toxic gases that have the potential to poison people.


===Toxins===
==Toxins==
''Main article: [[Gases]]''
''Main article: [[Gases]]''


Toxic gases can bring about many forms of harm to the station, and are dangerous if left unattended because of the tendency of passengers to blindly open doors. These gases are noticeable at high concentrations, as they appear as clouds or smoke. All of these gases are filtered by the scrubber network, and they can be sucked up by [[Atmospheric_Technician#Equipment|Portable Scrubbers ]] considerably faster. To contain the spread of these gases, you’ll want to use [[Atmospheric_Technician#Equipment|Holofan Projectors]], inflatable walls or doors, and if need be, you can weld some airlocks closed to prevent entry, just make sure the gas you're dealing with is not flammable.
There are many toxic gases some species (like Harpies) are hypersensitive to toxins, some species (like Voxes) are poisoned by Oxygen. It's important to not leave them unattended as not many people know what that bright green gas is on the other side of the door, and will walk in there without knowing that they will be dead in 10 secs. it's important that you use your equipment given to you to keep people out of the affected area and siphon the gases out as safely and fast as possible.

== Pumps ==
== Atmospheric Devices ==
Pumps gas to the other side based on the set pressure. Blocks gas from passing through if toggled off. Comes in two varities:
 
[[File:Gas_pump.png]]
 
[[File:Gas_pump_interface.png]]
 
Standard gas pump. Pumps gas along based on internal and external pressure. Has a maximum throughput of 4.5 Mpa. Mostly used to act as a valve to allow/disallow gas to flow from one pipe to another. Works very well in high pressure pipes but looses effectiveness when the pressure is lower. Regular gas pumps are more effective in lower pressure systems but will lose efficiency as the volume of gas rises.
 
At lower pressures a gas pump is generally a better option at moving gas.
 
[[File:Volumetric_gas_pump.png]]
 
[[File:Volumetric_gas_pump_interface.png]]
 
Volumetric pump. Pumps gas along based of internal and external mole amount. Has a maximum throughput of 200 L/s. Acts exactly like a gas pump but works off of mole amount instead of pressure. can move about twice as much gas compared to a regular gas pump if conditions are right.
 
For extremely high pressure pipes a volumetric pump is generally a better option at moving gas.
 
In certain cases volumetric pumps are also better if you are using huge quantities of gas.
 
== Manual Valves ==
Acts like a switch that either allows gas to flow through, or prevents it from flowing through. Can be toggled on and off.

== Gas Mixer ==
[[File:Gas_Mixer.png]]
[[File:Gas_mixer_interface.png]]
A gas mixer is a fancy version of the gas pump. Operates as a pressure pump, with associated limitations. It allows you to combine the gas flow of two different pipes and mix them into a single pipe. The gas mixer will combine the contents of two different pipes and will give you the option of setting the percentage of throughput you want on each of the input pipes. The primary port will be parallel with the output while the side port will be perpendicular.
Gas mixers are essential for distro as the station's atmosphere is 20% oxygen and 80% nitrogen. Gas mixers are also used for the combination of two different gases to create a new gas such as a common burn-mix.
If the gas mixer is toggled off then it will not allow any gas to flow through.
If both inputs are set to receive gas then both inputs must have gas flowing through them for the pump to work. For example, if the mixer is set to mix gas at a 80 to 20 ratio and the input pipe at 20% has no gas then the mixer will not allow the input pipe with 80% gas to flow through and vice versa.
== Gas Filter ==
[[File:Gas_Filter.png]]
[[File:Gas_filter_interface.png]]
Gas filters are another special type of gas pump. Operates as a volume pump, with associated limitations.  Gas filters are primarily used to extract a specific individual type gas from a pipe. They function similarly to the gas mixer, except they have one inlet port and two output ports. When gas flows through a mixer the selected gas to be filtered out will exit the perpendicular outlet port while all other gases will continue to flow down the parallel outlet port. If you wish to filter out more than one gas you will need to set up gas filters in series for each specific gas.
Gas filters are used to extract each individual gas from the waste loop. This ensures that only one type of gas is present in each specific gas holding tank. Gas filters are essential when you are trying to target and isolate a specific gas.
Gas filters do not require both outputs to be connected to function if there is no gas selected to filter or the filtered gas is not present. In this case the filter will act as a simple straight pipe segment. However, The filter will not allow gas to flow if the selected gas is present and there is no pipe connected to the perpendicular filter port.
== Vents ==
[[File:Gas_vent.png]]
Gas vents come in three varieties: Standard, Dual-port, and Passive.
All gas vents are solely used to move gas from pipes into the surrounding atmosphere. Gas vents are commonly used in conjunction with the distro loop to distribute breathable air to the station. Gas vents and the distro system are responsible for replenishing the atmosphere on the station.
A standard air vent will only allow a maximum pressure of 101.3 kPa to flow. If the external pressure is higher than the limit, no gas will flow out of the vent. Requires power to function.
A dual-port air vent is exactly like a standard air vent but it has two inlet connection ports.
A passive air vent does not require power and will allow any pressure to flow in '''both''' directions depending on the internal and external pressures. If the internal, or pipe pressure, is higher than the external, or outside atmosphere, Gas will flow out. The opposite is true if the external pressure is higher than the internal pressure. Passive air vents are mostly used in the mix tank and [[Supermatter]] chamber where very high pressures are needed.
== Air Scrubber ==
[[File:Air_Scubber.png]]
Air scrubbers slowly suck gas out of the surrounding atmosphere and can be found spread around the station. Mostly used in the waste loop, air scrubbers will syphon gas out of the atmosphere and shunt it along the waste loop where the gas will then be recycled and filtered into the gas holding chambers.
Air scrubbers must be powered and connected to an outlet port in order to function. A properly functioning air scrubber will be glowing blue.
== Air Injector ==
[[File:Air_injector.png]]
Air injectors have one purpose. They simply exist to only allow gas to flow from a pressurized pipe into the surrounding atmosphere. This handy little tool are useful when you want to inject a gas into an area but not allow any backflow. usually used with a filter/injector combination to single out a specific gas and pump it into a holding chamber.
Air injectors have a maximum output pressure of 9000 kPa.
== Pneumatic Valve ==
[[File:Pneumatic_valve.png|72x72px]]
Pneumatic valves have three ports: control, inlet, and outlet. Like manual valves, pneumatic valves permit bidirectional flow between the inlet and outlet, but only if the pressure at the control port is high enough.
To turn a pneumatic valve on, the control pressure must be at least 1 atm higher than the lowest pressure connected to the pneumatic valve, i.e. the lesser of the inlet and outlet pressures. The direction of flow between the inlet and outlet is from higher to lower pressure.
The flow rate limit of the pneumatic value is linear (proportional to control pressure) in a small region above the on threshold. It then saturates at 200 L/sec.

== Connecter Port ==
[[File:Connecter_port.png]]
Connecter ports are solely used to transfer gas from a pipe into a canister and vice versa. Wrench a canister on top of a connecter port to connect them. A connected canister will allow gas to flow until the pressure evens out.
== Canisters ==
[[File:Canister.png]]
[[File:Canister_interface.png]]
Canisters are used to hold and transport gas. Drag a canister over to a connecter port and use a wrench to connect it. If the connecter port's internal pressure is higher than the canister pressure, gas will flow into the canister until the pressure evens out.
If the canister has a higher pressure gas will flow out until the pressure difference is even. Canisters can release gas in different ways depending on the situation. Gas will only flow out if the release valve is toggled open. If the release valve pressure is lower than the external pressure, no gas will flow out.
* If the canister is wrenched to a connector port, gas will flow into the connector port.
* If a oxygen tank is inserted into a canister, gas will flow into the oxygen tank.
* If the canister is not connected to anything, gas will flow out into the surrounding atmosphere.
== Gas Miner ==
[[File:Gas_miner.png]]
Gas miners create new gas from nothing and are currently used to make sure the station has an infinite amount of a specific gas. Gas Miners come in different types and create different types of gas. A oxygen miner will create oxygen gas while a plasma miner will create plasma gas. Gas Miners can be found in Atmospherics inside each gas holding chamber.
== Gas Recycler ==
[[File:Gas_recycler.png]]
Gas recyclers are used to recycle waste gasses like CO2 into breathable oxygen. They require a lot of pressure to work, more than is created by simply breathing. They also require the waste gas to be heated to around 300°C, thus a heater and a freezer are required for it to work. They recycler loop can be filled with N2 to boost the pressure.

The gases are the most important part of Atmospherics. There are currently 9 gases in the game, each of them has its own Specific Heat Capacity and Molar Mass. The standard air mix on the station is 21% oxygen and 79% nitrogen at 101.325kPa and 20°C or 293.15K. Most of them can be created using [[Pipes and vents#Gas_Miner|Gas Miners]] or created in combustion reactions.

The Basics of Atmos

Atmos seems complicated on it's surface, but it's easier to understand once you learn the terms and how gases work.

Pressure

Pressure is measured in kPa (Kilopascals). A safe amount of kPa is 80-140 kPa. If kPa falls under or over that amount, most creatures will start to take barotrauma damage. Most atmos devices are set to 101.3 kPa. Pressure rises as temperature rises, and lowers as temperature lowers. Gases will always try to flow from higher pressure to lower pressure to create an equilibrium. It's important to be mindful of the pressure in a room or pipe before you open a door or unanchor a pipe. Most atmospheric devices clog around 4500 kPa, some only clog at 9000 kPa, and some don't clog at all.

Temperature

Temperature is measured in Celsius and Kelvin. A safe amount of temperature varies from species to species, the temperature a room should be is around 20°C (293.15K) as that's safe for all species. Heat and cold will always try to spread to create an equilibrium. Be mindful before you open a door or unanchor a pipe. Remember that space is naturally cold, so any spaced rooms will be very cold after you patch them up.

Mols

The exact volume of gases is measured in mols. It is important to pay attention to the exact mols of gases, such as dealing with the TEG or toxic gases that have the potential to poison people.

Toxins

Main article: Gases

There are many toxic gases some species (like Harpies) are hypersensitive to toxins, some species (like Voxes) are poisoned by Oxygen. It's important to not leave them unattended as not many people know what that bright green gas is on the other side of the door, and will walk in there without knowing that they will be dead in 10 secs. it's important that you use your equipment given to you to keep people out of the affected area and siphon the gases out as safely and fast as possible.

Pipes, Vents and Other Atmospheric Devices

General Information

All gases can flow through the various pipes found in the game. Gas will always attempt to flow from higher pressure to lower pressure. If a gas is not in a pipe, canister, or tank, it will be in the atmosphere and will interact with other objects.

Gas will always try to even out the pressure. For example, if a empty canister is connected to a pipe pressurized at 4500kpa, the canister will also only be pressurized to 4500kpa. If a canister pressurized at 9000kpa is connected to the same pipe, gas will flow out of the canister until a even pressure is acquired.

If pressurized pipes get unwrenched they will dump all of their contents into the surrounding atmosphere and will, depending on the pressure level, violently blow the wrench user away. You will know if you are unwrenching a pressurized pipe if you get the message stating "A gush of air blows in your face... Maybe you should reconsider?" It is good practice to always use your gas analyzer on every pipe before unwrenching to ensure it is depressurized.

All pipes can be unwrenched to disconnect them from others. By using a welder on a unwrenched pipe segment you can deconstruct it into steel.

A broken or unconnected segment of pipe WILL NOT allow gas to pass through. Do not worry about all your gas escaping out of a broken or unconnected pipe segment.

Most pumps, mixers, and filters do not require power to function. Only air vents and scrubbers require power. You can shift-click on a segment to examine it to see if it is powered.

Pipes

Allows gas to flow freely. Comes in four shapes. Straight, Elbow, 3-way-juntion, 4-way-junction.

Image Name Description

gas pipe bend A elbow segment of pipe.
gas pipe T junction A three way junction segment of pipe.

The primary port is parallel with the output while the side port is perpendicular. If one input is missing, it will not allow gas flow.
Gas Filter Filters out a selected gas into another pipeline. Has a maximum throughput of 1000 L/s, clogs at 4500 kPa. Filtered gas will exit out of the perpendicular outlet while all other gases continue to flow down the parallel outlet.

Pneumatic Valve Has three ports: Control, inlet, an outlit. Allows gas flow like a manual valve, but only if the pressure at the control port is high enough. To turn it on, the control port must be at least 1 atm higher than the lowest pressure connected to the valve. I.E the lesser of the inlet and outlit pressure.
Canister Used to hold and transport gas without the use of pipes. Use a wrench to connect a canister to a connector port. You can put air tanks into canister to fill them with whatever gas is in the canister.
Connector Port Used to transfer gas from pipes into canisters. Gas will flow into the canister until pressure evens out between the connector port and the canister. Use gas pumps to force more gas in/out of canisters.
Gas Miner Creates new gases from nothing, used to make sure stations have an infinite amount of a specific gas. Stations usually only come with an oxygen and nitrogen miner. Found in gas chambers in atmos.
Gas Recycler Used to recycle carbon dioxide and nitrious oxide into oxygen and nitrogen, respectively. Requires power, 3000 kPa and the gas to be 300°C to work.
Gas Condenser Condenses an gas into liquid.
Radiator Used to transfer the temperature of a room to the gas in pipes.
Freezer/heater Connected to pipe networks to heat up the gas inside. Has hellfire variants.
Portable Scrubber Works just like an air scrubber, but you can pull it around! Anchor it down to have it filter harmful gases out of the air.
Space Heater A portable heater used to regulate temperatures in certain rooms. Anchor it down and click the interact button to make it work.

Design Examples

Pressure Relief Valve

This pressure relief system drains the air inside to space if the pressure exceeds 1 atm, which can be used to guard against accidental station overpressure events. A passive vent inside (1) is connected to the control and the inlet. Another passive vent in space (2) is connected to the outlet. Since the outlet pressure is 0 kPa, then the pneumatic valve will only be on if the inside pressure exceeds 1 atm. When that happens, air from inside is transferred into space until the inside pressure is equal to 1 atm.

Turning Completeness

Pneumatic valves make atmos turing-complete.

Introduction

The gases are the most important part of Atmospherics. There are currently 9 gases in the game, each of them has its own Specific Heat Capacity and Molar Mass. Most of them can be created using Gas Miners or created in combustion reactions.

Gases

Gases in SS14
Gas Description Specific Heat Capacity Molar Mass (g/mol)
Oxygen
 Colorless, reactive gas that humans need to breathe to stay alive. Key oxidizing agent in most combustion reactions. 20 32
Nitrogen
 Colorless, odorless, inert gas. Somehow, slimes and voxes breathe this. 30 28
Carbon Dioxide
 Colorless, odorless, relatively inert gas. Exhaled by creatures that breathe oxygen. Toxic in high enough quantities. The reason why atmospheric technicians are employed. 30 44
Plasma
 Purple, putrid, highly-combustible, and toxic gas. Combusts in the presence of oxygen, but will not ignite on its own. Unfortunately, it is also vitally important to industrial and scientific activities aboard Nanotrasen stations. 200 120
Tritium
 Green, highly-combustible, and radioactive. Combusts in the presence of oxygen. It is formed by the combustion of Oxygen and Plasma. To form Tritium, there must be 96 times more Oxygen than Plasma during the reaction. If there is too much Plasma, the reaction will produce Carbon Dioxide instead. 10 6
Water Vapor
 Water in gaseous form. Due to the unique environment of space, does not condense into liquid water. Harmful to slime people. 40 18
Miasma
 Purple, foul-smelling gas. Breeds disease, toxic, and harmful in sufficiently large concentrations. A by-product of nasty biological processes, including rotting bodies. 20 44
Nitrous Oxide
 Colorless, Otherwise known as "laughing" or "sleepy" gas, it acts as a sedative to non-slimes and is toxic in very high concentrations. Unfortunately, this stuff is exhaled by slimes. Formed from Frezon and Nitrogen 40 44
Frezon
 Blue-greenish gas. Used as an industrial coolant. Used recreationally by some for its euphoric effects, before their lungs freeze out. It has a high value and is made by mixing cold Tritium and Oxygen. 600 50
