TAILIEUCHUNG - Lecture Thermodynamics: An engineering approach (8/e): Chapter 14 - Yunus A. Çengel, Michael A. Boles

Chapter 14 - Gas-vapor mixtures and air-conditioning. In this chapter, we consider the air–water-vapor mixture, which is the most commonly encountered gas–vapor mixture in practice. We also discuss air-conditioning, which is the primary application area of air–water-vapor mixtures. | Chapter 14 Gas-Vapor Mixtures and Air-Conditioning Study Guide in PowerPoint to accompany Thermodynamics: An Engineering Approach, 8th edition by Yunus A. Çengel and Michael A. Boles 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 = kJ/kg K, the enthalpy of the dry air is given by (assuming the reference state to be 0oC where the reference enthalpy is taken to be 0 kJ/kga) The assumption that the water vapor is an ideal gas is valid when the mixture temperature is below 50oC. This means that the saturation pressure of the water vapor in the air-vapor mixture is below kPa. For these conditions, the enthalpy of the water vapor is approximated by hv(T) = hg at mixture temperature T. The .
