Изобретение относится к области учебных и наглядных пособий и может быть использовано в учебном процессе ВУЗов. Сущность изобретения заключается в том, что образец помещают в тонкую эластичную герметичную оболочку так, чтобы там не было воздуха, и устанавливают в дополнительную емкость. В емкости размещают образец исследуемого материала. Емкость совместно с капиллярной трубкой и дополнительную емкость совместно с капиллярной трубкой заполняют равными объемами рабочей жидкости до верхних видимых срезов капилляров. Нагружение заданным давлением образцов и производят от баллона со сжатым воздухом через вытеснитель жидкостью другого цвета. Замеряя разность уровней рабочей жидкости по границе цвета в капиллярах, определяют пористость сжимаемых и набухаемых тел при любых заданных давлениях.The invention relates to the field of educational and visual aids and can be used in the educational process of universities. The essence of the invention lies in the fact that the sample is placed in a thin elastic hermetic casing so that there is no air, and installed in an additional container. In the tank place a sample of the material under study. The container together with the capillary tube and the additional capacity together with the capillary tube are filled with equal volumes of the working fluid to the upper visible sections of the capillaries. Loading the specified pressure of the samples and produce from a cylinder of compressed air through the displacer with a liquid of a different color. Measuring the difference in levels of working fluid along the color boundary in the capillaries, determine the porosity of compressible and swellable bodies at any given pressures.
