SUMMARY
The discussion focuses on calculating entropy and enthalpy for a system starting at 100 bar and 260°C, where the saturation temperature is 311°C. The user seeks to determine the dryness fraction (x) to compute availability using the formula availability = (h-h0) - T0(s-s0). The specific equations for entropy (s = sf + xsfg) introduce two unknowns, necessitating a method to compute s and h. The ASME steam tables are recommended for accurate calculations.
