Feb 2, 2011 · Thermodynamic properties of liquid and gaseous air. The enthalpy is taken as zero at an arbitrary point. The entropy is taken zero for the solid air at 0K. Air is a mixture mainly consisting of diatomic gases. Therefore its heat capacity at close to normal temperatures and pressures may with good accuracy be taken equal to. where.

Under standard atmospheric conditions (25 °C and pressure of 1 bar), the dynamic viscosity of air is 18.5 μPa·s, roughly 50 times smaller than the viscosity of water at the same temperature. Except at very high pressure, the viscosity of air depends mostly on the temperature.
At 20°C, the dynamic viscosity of water is approximately 1 × 10 − 3 Pa.s, while air's dynamic viscosity is 1.8 × 10 − 5 Pa.s. For liquids like water, viscosity decreases with an increase in temperature, while for gases like air, viscosity increases with an increase in temperature.
