The system treated in this work was proposed for the working fluid which can be used in the air cooled absorption chillers. By our research group the basic thermodynamic properties such as density, viscosity, vapor pressure, and heat capacity were measured. As a continuation of our study, the surface tension on the ternary system (LiBr + 1, 3-Propanediol + water) was measured using capillary rise method. The objective of this study is to measure the reliable thermodynamic data and provide the basic information for potential use. The measurement of surface tension of ternary system was made with varying temperature and weight percent of lithium bromide. The weight ratio of LiBr to 1, 3-propanediol is constant of 3.5 : 1. The surface tension values were measured at the temperature range from 298.15 to 323.15 K, and the LiBr concentration ranges up to 60 mass %, respectively. The measured data were successfully correlated with the simple polynomial equation and the average absolute deviation (AAD) from the experimental data was found to be within 0.11%.
