The article presents data on the cost of construction and economic efficiency of similar objects of pumped storage hydroelectric power plants (PSHPP) in world practice and in Uzbekistan. Development of measures to reduce head losses in intermediate channels of hydraulic systems and increase their efficiency is urgent issues. The authors assess the importance of the data obtained on the example of new design schemes for small hydroelectric power plants and pumped storage power plants of the Tuyamuyun hydroelectric complex, selected as an object of research.

This article discusses the construction of a mathematical model of accelerated chemical-technological processes. Usually, in practice, the problem of building models of multi-stage processes, as a rule, is complicated by the universality, uncertainty and nonlinearity of the objects being modeled, the complete or partial lack of expert experience and an analytical description of dependencies. Mathematical models describing chemical technologies are considered to break down the state into discrete stages. The study below allows us to recommend stage processes to be considered as continuous functions.
