Pipes and vents

WIP

All gases can flow through the various pipes found in the game. Gas generally flows from higher pressure to lower pressure.

Pipes

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

Image	Name	Description
	gas pipe straight	A straight segment of pipe.
	gas pipe bend	A elbow segment of pipe.
	gas pipe T junction	A three way junction segment of pipe.
	gas pipe fourway	A four way junction segment of pipe.

Pumps

Pumps gas to the other side based on the set pressure. Blocks gas from passing through if toggled off. Comes in two varities:

Gas Pump. Standard 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.

For low pressure pipes a volumetric pump is generally a better option.

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 high pressure pipes a regular gas pump is generally a better option.

Valves

Acts like a switch that either allows gas to flow through, or prevents it from flowing through. Can be toggled on and off.
