Entropy Facts For problem solving,states often are shown on property diagrams having specific entropy as a coordinate:the temperature-entropy and enthalpy-entropy(Mollier)diagrams shown here 6 2013-3-6 6 Entropy Facts ►For problem solving, specific entropy values are provided in Tables A-2 through A-18. Values for specific entropy are obtained from these tables using the same procedures as for specific volume, internal energy, and enthalpy, including use of (Eq. 6.4) for two-phase liquid-vapor mixtures, and (Eq. 6.5) for liquid water, each of which is similar in form to expressions introduced in Chap. 3 for evaluating v, u, and h.
