Aspects of finding the minimum velocity of self-purification in storm sever networks

Kalinin А.V.

Abstract

Aspects of finding the minimum rate of self-purification in storm sever networks are considered. The mechanism of solid particles movement caused by turbulence flow is considered. Performed analysis of storm sever networks building regulation in different countries has shown, that it is necessary to set clearer criterions for determination of runoff water minimum velocity in pipes. Results of the experimental research of using Shields and Galilee parameters for finding limits between different forms of solid particles movement caused by fluid flow are presented.

Forming the surfaces on fourangle curved plan

Ivanov V.N.

Abstract

The article concerns the questions of forming of the modified Coon's surfaces with inclined plane or space curved support lines on four angle plan. Using the inclined curved lines as support lines for construction of modified Coon's surfaces allows to receive many new forms of space constructions. There regards questions of erecting of the space lines on given curved four angle plan. There shown drawings of modified Coon's surfaces made with the help of 'MathCad' system.

Influence on polarization of samples polivinilchloride engine oil components

Bendik M.M., Khodyakov A.A., Soloviov D.E., Abu-Nidjm Ramsi Khasan Jusef -.

Abstract

It has been studied how semi-synthetic motor oil affects the polarization of polyvinyl chloride samples. It has been defined that the oil components influence the process of polyvinyl chloride polarization. We have showed that the input and exhaust motor oil contains polar components which bring to the density growth of the polyvinyl chloride charge being guided by the electric field direction. The injected charges initiate a chemical interaction of oil components. The water higher rate containing in the exhaust oil is reflected in the parameters of charge density of the samples, as well as of the activation energy of the electrically active defects.
