Research and calculations of non-uniform motion are very important from a practical point of view and have certain features for different states of flow, analysis of the shape of free surface curves, as well as the design of many hydraulic structures. When considering these issues, the concepts of specific cross-sectional energy and critical depth are used. The current trend of technology development in the educational process is based on Internet communications, instant online calculations and mobile microprocessor gadgets with appropriate software. The presented experimental project of educational and methodical material with web forms of online calculation of individual tasks is a variant of the modern competitive online environment on the Internet. Further direction of development - addition of methodical video, audio and graphic elements. Analysis of web analytics will gradually simplify the interface and choose the most effective set of modern formats for teaching materials. Computer on-line calculations allow to change the initial data and to introduce elements of modeling and in-depth study of theoretical positions using one typical example in the form of a web form
Sewage systems are an important component of the life support system, which, in particular, determine the ecological condition in the settlement. The durability of the laid network depends on many factors, one of which is their corrosion resistance. The number of accidents on the site and the number of necessary repairs are also related to this factor. The purpose of the work was to study the factors that have the greatest influence on the corrosion resistance of sewer pipelines, with the aim of increasing their service life and reducing the number of accidents. The analysis used information obtained during the practical operation of sewer pipelines in the city of Kyiv. The data of a group of pipelines with diameters from 500 to 1500 mm were analyzed. The planning of the active experiment was made on a sample of data for 25 years of operation. The presented study was carried out in the statistical package STATGRAPHICS. A full factorial experiment was conducted. According to the results of the work, the total number of determining factors was reduced. Based on the methods of statistical analysis, the following conclusions were obtained: a statistically significant relationship was established between the use of concrete pipes with low speed and the largest number of pipeline accidents. The material of the pipeline and the speed in it turned out to be the factors that have the greatest influence on the life of the pipeline and the number of accidents on the pipeline.
Four different options of modern engineering calculation for solving one standard problem were studied. Four different modern options for solving one standard problem based on the new author's method of three K123 commands. The basis of the author's method is the geometric content and formulation of the problem of determining the hydrostatic pressure on a flat surface using the example of a standard typical problem of hydrostatics. The algebraic component of the implementation of the problem solution is used as an auxiliary calculation technology.A full factorial experiment was conducted. According to the results of the work, the set goal was achieved - the total number of factors was reduced. Based on the methods of statistical analysis, the following conclusions were obtained: a statistically significant relationship was established between the use of concrete pipes at a low speed and the largest number of pipeline accidents. The material of the pipeline and the speed in it turned out to be the most influencing factors on the life of the pipeline and the number of accidents on the pipeline. The purpose of the presented work is to show the relevance of the development of scientific foundations, new algorithms and corresponding calculation technologies in modern engineering hydraulic calculations, which include individual achievements - unfortunately missed in the domestic educational literature - of the fifth technological order: cybernetics, computers, numerical methods, communication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
