Major scientific or scientific and technical results received: - a mathematical model of the viscous fluid flow in the pipeline is structured in the presence of fluid overflow and the narrowing of the cross section, which is based on the Navier-Stokes system of equations in a two-dimensional rectangular coordinate system with a special type of boundary conditions; - a mathematical model of the deformation process of steel tanks of spherical configuration with the use of data concerning the displacement of their surface points was developed; - a mathematical model of the metabolic process in the body on the basis of the Lotte-Volterra model was developed. The scientific and methodical products were obtained: a software package for the implementation of models that allow assessing the stress-strain state of pipelines based on known displacements of its surface points, assess the volume of these sources, and assess the magnitude of the zone of negative impact of leakage products on the environment.
