In fact, in (4) the weight of the submerged part of the sliding wedge is considered through the effective unit weight of soil which is reflected in the force equilibrium diagram, and then [K.sub.a] is calculated.
In constructing any phase diagram, whether oxide or alloy, it is necessary to answer the following questions: (1) What are the most effective ways of preparing the diagram/library, (2) What are the best techniques to analyze the compositions so as to ascertain the phases present and construct the tie-line relationships, (3) How can it be determined whether the result represents equilibrium at the given conditions; how well does it match the equilibrium diagram prepared using bulk methods; how does it compare with the calculated diagram; (4) How well does the library reproduce the relevant properties of the bulk materials; (5) How can the property information collected for the library be rapidly assessed.

The partial pressure [p.sub.i] is related to the mole fraction [x.sub.i], of constituent i in the liquid phase (through the vapor pressure equilibrium diagram of the mixture), which is defined as:
To better understand this behavior and specifically the comparatively large observed ethanol intake, the vapor-liquid equilibrium diagram of the ethanol/toluene/isooctane ternary blend has to be established and the equilibrium in the presence of various ethanol-hydrocarbons mixtures with variable concentrations and activities should be studied quantitatively.
