A Manometric Method of Measuring the Apparent Density of Granular Materials

摘要

Results from theoretical and experimental studies of the manometric method of monitoring the density of granular chemisorbents in a complex determination of their thermophysical characteristics are presented. The processes that occur in the course of measurements are described, the static characteristic of the measuring plant is investigated, the errors are determined, and computational dependences and recommendations on the use of the method are presented. The mutual influence of the processes involved in the measurement of thermal conductivity and density is estimated. It is established that the apparent density of granular materials may be monitored by means of a relative manometric method with compensation for the influence of atmospheric pressure on the measurement results.
