![]() ![]() The thermodynamic properties of air along the saturation curve are given in Table 1 these properties for the liquid and gaseous air-in Table 2. Basis are thermodynamic properties of humid air. Keywords: Thermodynamic properties of dry air, thermophysical properties of dry air, Peng-Robison EoS, cubic EoS. Enter air temperature and relative humidity and calculate the dew point with one click. The equilibrium dissociation degree can be calculated according to the Saha equation. the Eq.s developed by The International Association for the Properties of Water and Steam (IAPWS). Friend, Thermodynamic Properties of Air and Mixtures of Nitrogen, Argon, and Oxygen from 60 to 2000 K at Pressures to 2000 MPa, J. ![]() This implies the transition of air into the plasma state. Their equilibrium concentration can be derived from the isotherm equations of the respective reactions.Īt temperatures higher than 2000 K and moderate pressures the nitrogen and oxygen start to dissociate, and at temperatures exceeding 4000 K and atmospheric pressure the ionization of oxygen, nitrogen, and other components becomes evident. It is capable of calculating the properties density, specific isobaric heat capacity, specific isochoric heat capacity, specific enthalpy, specific entropy, specific internal energy, dynamic viscosity and kinematic. Based on the most accurate pure fluid and mixture models currently available. This calculator calculates thermodynamic properties for water as function of pressure and temperature. NIST Reference Fluid Thermodynamic and Transport Properties Database. The nitrogen reacts with oxygen producing various oxides: N 2O, NO, NO 2, NO 3. A lot of fluids are available including Air, Water, R134a. The normal condensation temperature of air is -191.4☌, the normal boiling temperature -194☌.Īt elevated temperatures air undergoes some physicochemical transformations. program that calculates adiabatic combustion temperature and equilibrium mole fractions of selected fuels with with air or pure oxygen. Liquid air at atmospheric pressure behaves practically as an ideal solution following the Raoult's Law. EES distributable program that calculates the thermodynamic properties of selected real fluids (in SI and Eng units) given any two independent properties. The normal (at 0.1013 MPa) boiling (condensation) temperature of the oxygen is equal- 183☌, that of the nitrogen -195.8☌. Where v denotes specific volume u is specific internal energy R is the gas constant for air.Īt low temperatures the air is liquified. ![]()
