What is ENGINEERING THERMODYNAMICS...?


The term thermodynamics is derived from the Greek Word therme (heat) and dynamics (power or motion); thus thermodynamics means heat power or heat in motion. Thermodynamics is defined as the science of engineering that deals With the storage of energy, entropy, heat and Work, mutual conversation of heat and Work, exchange of energy and those properties of substances that govern the relation between heat and Work. Earlier, thermodynamics Was considered as a subject of science by Joule (1818-1889), Kelvin (1824-1907), Clausius (1822-1888) and Carnot (1792-1832). Later, Gibbs (1839-1903) extended its scope and now it is extensively used in branches of science and engineering to analyze physical and chemical changes. Experimental observation is the basis for thermodynamics. Based on these observations and results, certain basic laws are developed Which are known as the Zeroth, First, Second and Third laws of thermodynamics. A large part of the subject of thermodynamics deals With a study of energy. Energy can be defined as a capacity to produce change. The energy output of an I.C. engine supplies the capacity to move from one location to another. The energy output of a power plant supplies the capacity to produce a Wide variety of changes to operate motors, television sets and lights, etc.


Thermodynamics is the science of energy transfer and its effect on the physical properties of substances. It is based upon observations of common experience which have been formulated into thermodynamic laws. These laws govern the principles of energy conversion. The applications of the thermodynamic laws and principles are found in all fields of energy technology, notably in steam and nuclear power plants, internal combustion engines, gas turbines, air conditioning, refrigeration, gas dynamics, jet propulsion, compressors, chemical process plants, and direct energy conversion devices.
