Abstract
The properties of a plot of the isotherms and phase boundaries of water-steam-air mixtures on an enthalpy-composition diagram for constant total pressure are shown to permit graphical constructions enabling surface conditions, heat and mass transfer rates, and equipment size to be deduced for convection, steam-drum and radiant drying plant, cooling-towers, condensers, gas coolers and trickle coolers. A chart for atmospheric pressure calculations is presented, together with data from which charts for other pressures may be simply calculated. The graphical method may also be applied to other systems involving phase changes.Keywords
