【 摘 要 】

On the basis of the known hydraulic dependences, which describe the fluid flow regimes in gravity pipe lines, the results of bench experimental studies on various types of pipeline materials and internal protective coatings have been analyzed in an automated mode. The simulation technique algorithm and the automated program are constructed in such a way as to be a kind of experiments' catalogue (database) carried out on a universal hydraulic bench. The program content and the requirements to input and output information are presented herein. The results of an automated processing of the experimental data are given in the form of tables and graphical dependences, which characterize the liquid gravity flow regime depending on the degree of the pipelines roughness made of different materials. The target of the program is to provide a wide application of its results by the designers as tool in their design works when designing gravity water discharge lines, as well as in construction, modernization and renovation of pipeline transport facilities focusing on the trenchless repair methods. The program has a special unit, which assesses and compares domestic and foreign methods of hydraulic calculations of pipe lines through the roughness coefficients determined by the formulas of Manning and N.N. Pavlovskiy.
