Abstract:

A program is in progress at this Laboratory to measure various thermophysical properties of sodium, potassium, cesium, and their vapors. Experimental values are presented for the pressure-volume-temperature properties of sodium vapor and the density of sodium liquid. Two equations of state are advanced for sodium, and properties of the saturated and superheated vapor are derived from these equations by a thermodynamic treatment, which is presented in outline form. Enthalpy, entropy, specific volume, and specific heat and compositional information weight fraction of dimer, weight fraction of tetramer, and average molecular weight are tabulated for some 800 selected vapor states in the temperature range from 1625 to 2575 deg F, and in the pressure range from 0.2 to 26 atm. Similar tables for potassium, which were previously reported in the Twelfth Progress Report, were computed from a saturated liquid base. These tables have been recomputed using properties of the monomeric gas as a base, and are published in this report.
