SUMMARY
The discussion centers on determining the specific enthalpy of a saturated vapor mixture with a relative humidity of 80% at a temperature of 30°C using a Mollier diagram. It is clarified that the mixture cannot be considered saturated due to the relative humidity being less than 100%. The reference state for calculating specific enthalpy is typically set at 0°C and 1 atm for pure species, although some tables may use 25°C. The Mollier diagram must specify the reference state for zero enthalpy to accurately perform the calculations.
