Заглавие : Capillary constant and surface tension of methane-helium solution Место публикации : Fluid Phase Equilibria. - 2013. - Vol.354. - С. 245-249 Примечания : Bibliogr. : p. 249 (21 ref.) ББК : 53 Предметные рубрики: ФИЗИКА Ключевые слова (''Своб.индексиров.''): adsorption--capillary constant--differential capillary method Аннотация: The differential capillary method has been used to measure the capillary constant a2 of methane-helium solutions in the temperature range from 95 to 175K at pressures up to 4MPa. The surface tension γ and adsorption have been calculated from the obtained values of a2 employing, in addition, literature data on the density of the liquid and vapor phases of the respective solutions. Equations, which approximate the temperature, pressure and concentration dependences of a2 and γ, are proposed Доп.точки доступа: Grishina, K. A.; Байдаков Владимир Георгиевич
