Description
Scitus Engineering Thermodynamics by Dorin Vasilescu
Thermodynamics is a branch of physics associated with heat and temperature and their relation to energy and work. It de?nes macroscopic variables, such as internal energy, entropy, and pressure that partly pronounce a body of matter or radiation. It mentions that the behavior of those variables is subject to general constraints that are common to all materials, not the peculiar properties of particular materials. These general constraints are expressed in the four laws of thermodynamics. Thermodynamics describes the bulk behavior of the body, not the microscopic behaviors of the very large numbers of its microscopic constituents, such as molecules. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, chemical engineering and mechanical engineering. Initially, thermodynamics, as applied to heat engines, was concerned with the thermal properties of their 'working materials', such as steam, in an e?ort to increase the e?ciency and power output of engines. Thermodynamics was later expanded to the study of energy transfers in chemical processes, such as the investigation of the heats of chemical reactions, which was not originally explicitly concerned with the relation between energy exchanges by heat and work. From this the study of chemical thermodynamics and the role of entropy in chemical reactions are evolved. Engineering Thermodynamics is characterised by exhaustive study of topics such as thermodynamic applications, powerplant engineering, refrigeration and automobile IC systems. The book highlights the various thermodynamics concepts such as temperature and gas laws, work and heat transfer, entropy, energy and its reversibility, and properties of gas and mixtures. The book also focuses the principles, concepts, and laws/postulates of classical and statistical thermodynamics to applications that require quantitative knowledge of thermodynamic properties from a macroscopic to a molecular level. The book follows a comprehensive approach such that engineering students, working professionals, and research associate can bene?t from the book.
