Thermal properties of air at different temperatures - density, viscosity, critical temperature and pressure, triple point, enthalpi and entropi, thermal conductivity and diffusivity and more. Thermophysical properties of air: Boiling temperature (at 1 bara): 78.8 K = -194.4 °C = -317.8 °F.
Based on available experimental data, the thermal conductivity of fluid air has been critically evaluated. A new set of recommended values is presented covering a pressure range from 1 to 1000 bar and a temperature range from 70 to 1000 K.
Air at a Pressure of 1 atm Functions. The functions below provide a means to evaluate the properties of air as a function of temperature. They were formulated by preforming regression analysis on the tabulated data presented in section 2.2.
2 lut 2011 · The behavior of the thermal conductivity of air is similar to the viscosity: in the liquid phase with growing temperature the heat conductivity decreases whereas in the gas phase-increases. At low pressures the temperature dependence is described by the equation:
