Abstract
Times New RomanA formulation is presented for the thermodynamic properties of propane. The equation of state is valid for temperatures from the triple point temperature (85.525 K) to 650 K and for pressures up to 1000 MPa. The formulation can be used for the calculation of all thermodynamic properties, including density, heat capacity, speed of sound, energy, and saturation properties. Comparisons to available experimental data are given that establish the accuracy of calculated properties. The approximate uncertainties of properties calculated using the new equation are 0.02 % in density, 0.5 % in heat capacities, 0.03 % in the speed of sound, and 0.01 % in vapor pressure above 170 K. Deviations in the critical region are higher for all properties except vapor pressure.Citation
