Prototype/Fluid
Mandatory properties
Inherits all properties from Prototype.
icon
Type: Types/FileName
icon_size
Type: Types/uint
The size of the square icon, in pixels, e.g. 32 for a 32px by 32px icon.
default_temperature
Type: Types/double
Also the minimum temperature of the fluid.
max_temperature
Type: Types/double
base_color
Type: Types/Color
Used by bars that show the fluid color, like the flamethrower turret fill bar in the tooltip, or the fill bar for the fluidwagon tooltip; and for the pipe windows and storage tank fill gauges.
flow_color
Type: Types/Color
Used only for pipe windows or storage tank fill gauges.
pressure_to_speed_ratio
Type: Types/double
flow_to_energy_ratio
Type: Types/double
Flow to energy ratio can't be negative.
Optional properties
heat_capacity
Type: Types/Energy
Default: "1KJ"
Joule needed to heat 1 Unit by 1 °C.
fuel_value
Type: Types/Energy
Default: "0J"
emissions_multiplier
Type: Types/double
Default: 1.0
Scales pollution generated when the fluid is consumed.
gas_temperature
Type: Types/double
Default: max value of double (1.7976931348623158e+308)
max_push_amount
Type: Types/double
Default: 1
When two fluids interact how much of it can be pushed at most.

Differing defaults
subgroup
Default: "fluid"
The value of this property may not be an empty string. It either has to be nil, or a non-empty string.
