Abstract : The Benedict equation of state and isobaric heat capacities at infinite attenuation were employed in determining the thermodynamic properties of NO at -80 deg to 220 deg F and up to 3000 psi. The coefficients for the equation were established from available experimental information on the volumetric behavior of NO, and the heat capacity was obtained from spectroscopic measurements. Specific values of volume, enthalpy, entropy, and fugacity were calculated for 27 different pressures at 11 temperatures. The data are tabulated along with the analytical expressions for thermodynamic properties. Experimental compressibility factors, pressure-compressibility factor, heat capacity (gas phase), temperature-entropy, and enthalpy-pressure diagrams are presented. The results obtained established at thermodynamic properties of NO throughout the temperature and pressure ranges of primary industrial interest. A sufficient number of states were included in the tabulation to permit 4-point linear extrapolation for many applications.
