Equations Useful for Gas Mixtures

In this appendix we derive several equations that are useful for working with flammability diagrams. Section 6-5 provides introductory material on the flammability diagram. In this section we derive equations proving that:

1. If two gas mixtures R and S are combined, the resulting mixture composition lies on a line connecting the points R and S on the flammability diagram. The location of the final mixture on the straight line depends ...
