The article dwells on the method for summarizing experimental data on hydrodynamics of one-phase filtration flows through packed heat-and-mass exchange apparatuses differing in configuration. Summarizing is performed using a modified generalized equation. The described method simplifies the work with experimental bulk data, helps to compare the packed heat-and-mass exchange apparatuses, assess their energy performance and find the ways for their industrial implementation in heat-and mass exchange equipment.
