Abstract: Study of pressure nonstationary flow relationships depends on necessity of their various applications. Nonstationary flows occur in various machinery, pressure pipes, oil refineries, in transportation of polymer materials. The subject matter of nonstationary flows study is to develop computation methods on running hydraulic-mechanical phenomena. Nonstationary flows often occur in closed cylindrical beds which can be of the following cross-section geometrical shapes: a) circular, b) rectangle, c) annular. For each case a mathematical simulation of flow has been developed, boundary conditions of the problem have been defined, and analytical solutions for velocity distribution relationships and power loss in effective cross-section. Solutions of all problems have been considered in case of general boundary conditions. Some special problems of important practical applications have been considered based on general solutions. Machine computations have been made and the results presented by graphs and design equations. Machine computations have been made and the results presented by graphs and design equations. Special cases of important practical applications have been discussed. Nonstationary flows generally occur while transportation of in various machinery, pressure pipes, oil refineries, various polymers
