Description

Used to mix two gases in proportions ranging from 0-100%. A must have for the Furnace. Input 1 is the straight thorough route, and Input 2 is the side entry.

Setting

The setting wheel is set in percent of input 1. Holding 'c' allows you to set the dial in 1 percent increments. It's possible to set the ratio with an arbitrary precision using the labeler or a Logic Writer, but the dial will always show rounded to the nearest percent when you look at it.

Temperature Dependence

The gas mixer will mix the input gases based on moles of gas in the ratio provided by the setting, but only if the gases at input 1 and input 2 are at the same temperature. This means if you're trying to mix Volatiles and Oxygen at a 2:1 ratio, make sure both input gases are at the same temperature.

While the gas mixer ignores input pressures, the mixer will take more moles of the colder gas than you would expect. For instance, if you set the gas mixer to a 1:1 ratio and both inputs contain just Carbon Dioxide, input 1 at 2000 K and input 2 at 1000K, it will take twice as much of the gas from input 2, so your resultant gas will be Carbon Dioxide at 1333.33 K.

Assuming you're mixing two identical gases with different temperatures, and the temperature of the hot gas at input 1 is "T1", the temperature of the cold gas at input 2 is "T2" and the mixer is set to "S" percent, then the resulting gas temperature will be given by this formula:

Tout = (T1 x 100) / (S + (100-S) x T1 / T2)

If you know your two input temperatures and your desired output temperature (which must be between T1 and T2), you can re-arrange this to solve for "S", which will tell you what to set the dial to in order to get the desired temperature:

S = (100/(T2-T1) x ((T1 x T2 / Tout) - T1)

Data Parameters

These are all parameters that can be written with a Logic Writer, Batch Writer, or Integrated Circuit (IC10).

Parameter Name	Data Type	Description
Lock	Boolean
Setting	float	Correspond to the percentage value of the Input 1
On	Boolean

Data Outputs

These are all parameters, that can be read with a Logic Reader or a Slot Reader. The outputs are listed in the order a Logic Reader's "VAR" setting cycles through them.

Output Name	Data Type	Description

Lock	Boolean
Setting	float	Contains the current Input 1 value in percent (60.5 for example)
Maximum	float	Value of 100
Ratio	Float	Contains the ratio corresponding to the Input 1 value (0.605, for the 60.5 value above)
On	Boolean
Requiredpower	Integer	In Watts. The Gas Mixer require 100W of power to function
