Fluid system

Liquids (note) are non-solid items like water and oil.

Behavior

Liquids can only exist inside pipes and certain buildings, meaning they cannot be carried by the player, moved using inserters, or dropped on the ground. They are counted in continuous fractions, rather than discrete integers. Liquids can be silently destroyed by removing buildings or pipes, mixing types of liquid, or at the output of a steam engine.

Machines

File:Chemical-plant.png Chemical plant	Changes liquid to other forms as well as crafting some recipes that require liquids.
Pumpjack	Extracts Crude oil from Oil fields.
Boiler	When fueled increases the temperature of water flowing through.

Flow mechanics

All types of liquid have the same properties, like their fluidity, density, and heat capacity.

Using water to generate power

Liquids can be used to generate power.

History

Water was the first liquid to be added to the game. In v0.9 the oil processing system, and therefore new liquids, including crude oil and petroleum gas, were added.

Notes

1. "Fluids" is the proper term for the concept this article is about, as it explains the properties and uses of both liquids and gases.
