A dielectric liquid - askarels (highly refined mineral oils and the newer non-inflammable insulating liquids) is used thoroughly free of air for insulating and cooling. Processing of assembled finished transformers is an important phrase of work in the transformer manufacture. Firstly‚ the insulated wire is wound about the cylinder. By applying heat to the unit while under vacuum‚ the

ENHANCING ENVIRONMENTAL PERFORMANCE BY GREEN PROCUREMENT: A CASE OF THE CONSTRUCTION INDUSTRY IN KENYA Abstract In recent years‚ the general awareness of the environmental impacts that industrial production gives rise to has radically increased throughout the world. Finding ways to minimise these impacts has become a major concern of the authorities in many countries. In order to promote a more sustainable industrial production‚ different incentives can be used. Among these incentives‚ the consideration

What is Chemical and Process Engineering? The branch of Engineering which is concerned with processes in which materials undergo a required change in composition‚ energy content or physical state at a reasonable cost and in the safest possible manner. History of Chemical Engineering For all intents and purposes the chemical engineering profession began in 1888. While‚ the term "chemical engineer" had been floating around technical circles throughout the 1880’s‚ there was no formal education

Since mechanical engineering isn’t taught in high school‚ young students don’t know much about it. Can you describe mechanical engineering? Mechanical engineering is by far the most broad-based branch of engineering. Most high school students associate the field with auto mechanics‚ but that’s an enormous misconception. Mechanical engineers today are concerned with the design‚ development and manufacture of a variety of energy conversion and machine systems. Those systems include aerospace‚ automotive

Environmental Engineering is a discipline of engineering devoted to the development and application of scientific knowledge through technology to eliminate or minimize adverse effects associated with human activities. It operates at four different levels: remediation of contaminated sites‚ treatment of effluents‚ pollution prevention‚ and care for future generations. Environmental engineering is fundamentally object-focused‚ rather than tool-based. It therefore draws from all other engineering disciplines

Currently‚ Mechanical engineering is becoming one of the most important fields in the world. Mechanical engineers are required in all types of fields‚ such as manufacture‚ repairing and maintenance. It is a subject of engineering which is combined by the principles of computer science‚ physics‚ material science‚ math‚ business and management. As for a professional mechanical engineer‚ you are not only required to know well the general knowledge of engineering‚ you are also expected to master diverse
