C 20 Capillary constant and surface tension of methane-nitrogen solutions: 1. Experiment [Electronic resource] / V. G. Baidakov, M. N. Khotienkova, V. N. Andbaeva, A. M. Kaverin // Fluid Phase Equilibria. - 2011. - Vol.301, №1. - P67-72 Рубрики: ФИЗИКА Кл.слова (ненормированные): MIXTURES -- OXYGEN Аннотация: The differential version of the method of capillary rise has been used to measure the capillary constant and calculate the surface tension of methane-nitrogen solutions. Experiments. have been conducted in the temperature range from 95 to 170K at pressures up to 4 MPa. Experimental data on surface tension have been compared with the results of calculations by thermodynamic models. Equations are given which describe the dependence of the capillary constant of a solution on its temperature and composition. \\\\Expert2\\nbo\\Fluid Phase Equilibria\\2011, v.301, p. 67-72.pdf |
