AbstractThe first law of thermodynamics states that the total energy of a system remains constant, even if it is converted from one form to another.

AbstractThe second law of thermodynamics stipulates that the total entropy of a system plus its environment cannot decrease; it can remain constant for a reversible process but must always increase for an irreversible process.

AbstractAs stated previously, classical thermodynamics is very much a mathematical discipline. Given that the defining equations are known, the theory is developed around multivariable calculus. The theory is actually quite elegant, but it does not predict how to estimate or calculate the fundamental quantities or the properties that characterize them. For this, a transition to statistical thermodynamics is required. Statistical thermodynamics starts with the kinetic theory of gases and treats fluids as made up of large assemblages of atoms or molecules. It can be a very detailed and extensive theory that extends well beyond the subjects of interest to this text. However, a smattering of statistical thermodynamics, including the kinetic theory of gases, will be useful for understanding a number of classical thermodynamics phenomena. A brief sojourn into the kinetic theory of gases is useful.

AbstractFrom a thermodynamic point of view, work is considered a macroscopic event, such as raising or lowering a weight or winding or unwinding of a spring. In this, chapter we talk about which work can be reversible or irreversible, and what do we mean by either of these processes.

AbstractA heat exchanger is a heat transfer device that exchanges heat between two or more process fluids. Heat exchangers have widespread industrial and domestic applications. Many types of heat exchangers have been developed for use in steam power plants, chemical processing plants, building heat and air conditioning systems, transportation power systems, and refrigeration units. The actual design of heat exchangers is a complicated problem. It involves more than heat-transfer analysis alone. The cost of fabrication and installation, weight, and size play important roles in the selection of the final design from a total cost of ownership point of view. In many cases, although cost is an important consideration, size and footprint often tend to be the dominant factors in choosing a design.
