    INTRODUCTION The study of thermodynamics is concerned with the ways energy is stored within a body and how energy transformations, which involve heat and work, may take place. One of the most fundamental laws of nature is the conservation of energy principle. It simply states that during an energy interaction, energy can change from one form to an...

    Stagnation Properties Consider a fluid flowing into a diffuser at a velocity , temperature T, pressure P, and enthalpy h, etc. Here the ordinary properties T, P, h, etc. are called the static properties; that is, they are measured relative to the flow at the flow velocity. The diffuser is sufficiently long and the exit area is sufficiently large t...

  • Bài giảng Thermodynamics: An Engineering Approach - Chapter 16: Chemical and Phase EquilibriumBài giảng Thermodynamics: An Engineering Approach - Chapter 16: Chemical and Phase Equilibrium

    Since the percent theoretical air is known, the N2 balance gives B. The H balance gives G. Then the C and O balances give two equations that relate the remaining three unknowns D, E, and F. Therefore, we need one more equation. To obtain this last equation relating the mole numbers of the products, we assume that the products are in chemical equil...

  • Bài giảng Thermodynamics: An Engineering Approach - Chapter 14: Gas-Vapor Mixtures and Air-ConditioningBài giảng Thermodynamics: An Engineering Approach - Chapter 14: Gas-Vapor Mixtures and Air-Conditioning

    We will be concerned with the mixture of dry air and water vapor. This mixture is often called atmospheric air. The temperature of the atmospheric air in air-conditioning applications ranges from about –10 to about 50oC. Under these conditions, we treat air as an ideal gas with constant specific heats. Taking Cpa = 1.005 kJ/kgK, the enthalpy of ...

  • Bài giảng Thermodynamics: An Engineering Approach - Chapter 13: Gas MixturesBài giảng Thermodynamics: An Engineering Approach - Chapter 13: Gas Mixtures

    The discussions in this chapter are restricted to nonreactive ideal-gas mixtures. Those interested in real-gas mixtures are encouraged to study carefully the material presented in Chapter 12. Many thermodynamic applications involve mixtures of ideal gases. That is, each of the gases in the mixture individually behaves as an ideal gas. In this sect...

  • Bài giảng Thermodynamics: An Engineering Approach - Chapter 12: Thermodynamic Property RelationsBài giảng Thermodynamics: An Engineering Approach - Chapter 12: Thermodynamic Property Relations

    Some thermodynamic properties can be measured directly, but many others cannot. Therefore, it is necessary to develop some relations between these two groups so that the properties that cannot be measured directly can be evaluated. The derivations are based on the fact that properties are point functions, and the state of a simple, compressible sys...

    The vapor compression refrigeration cycle is a common method for transferring heat from a low temperature to a high temperature. The above figure shows the objectives of refrigerators and heat pumps. The purpose of a refrigerator is the removal of heat, called the cooling load, from a low-temperature medium. The purpose of a heat pump is the trans...

    We consider power cycles where the working fluid undergoes a phase change. The best example of this cycle is the steam power cycle where water (steam) is the working fluid.

    Our study of gas power cycles will involve the study of those heat engines in which the working fluid remains in the gaseous state throughout the cycle. We often study the ideal cycle in which internal irreversibilities and complexities (the actual intake of air and fuel, the actual combustion process, and the exhaust of products of combustion amon...
