Accurate and extensive thermodynamic (heat capacity, heat of mixing, vapor pressure, solubility, density, and surface tension) and transport (viscosity) properties of working fluids are required for the research and reliable design of absorption refrigeration and heat pump systems. Densities, viscosities, and surface tensions for the H[sub 2]O + LiBr + LiI (salt mole ratio 4:1) and the H[sub 2]O + LiCl + LiNO[sub 3] (salt mole ratio 2.8:1) systems were measured at various temperatures and absorbent concentrations. Polynomial equations for densities, viscosities, and surface tensions of these two ternary systems were obtained as a function of absolute temperature by a least-squares method from the individual experimental data. The average absolute deviations between the measured density, viscosity, and surface tension data and the individual calculated values from these polynomial equations were 0. 19,1.66, and 0.57 % for the H[sub 2]O + LiBr + LiI system and 0.14, 0.54, and 0.24% for the H[sub 2]O + LiCl + LiNO[sub 3] system, respectively.
