- Module Goal: To familiarize you with the basic concepts of Phase Diagrams as a means of representing thermodynamic data.
- Module Objective: To familiarize you with the process of extracting quantitative compositional information from phase envelopes.
- 5.3: The Lever Rule
- P-x and T-x diagrams are quite useful, in that information about the compositions and relative amounts of the two phases can be easily extracted. In fact, besides giving a qualitative picture of the phase behavior of fluid mixtures, phase diagrams can also give quantitative information pertaining to the amounts of each phase present, as well as the composition of each phase.
