Perkins (2016): Reference Correlation of the Thermal Conductivity of Carbon Dioxide from the Triple Point to 1100 K and up to 200 MPa. Wagner (1994): A New Equation of State for Carbon Dioxide Covering the Fluid Region from the Triple-Point Temperature to 1100 K at Pressures up to 800 MPa. = CO2.transport_pT(pressure, temperature) = CO2.transport_rhoT(density, temperature) Just as with equilibrium properties, they can be calculated in two ways:ġ) as function of density in kg/m3 and temperature in K Transport properties have to be calculated both at once, since they depend on each other in the critical region. Enthalpy values multiplied by the quantity of steam give energy output. Saturated liquid heat capacity cs in kJ/(kg K) Calculation worksheets Indirect CO2 emissions from the consumption of purchased. The inputs must have the same size or one of them has to be a scalar. entropy = CO2.s_pT(pressure, temperature) entropy = CO2.s_rhoT(density, temperature)Ģ) as a function of pressure in MPa and temperature in KĮ.g. The validity range is not checked for the virial coefficients.Įquilibrium properties can be calculated in two ways:ġ) as a function of density in kg/m^3 and temperature in KĮ.g. Phase boundary functions return nan outside their validity range. Saturated vapor density rhoVapSat in kg/m^3 Saturated liquid density rhoLiqSat in kg/m^3 Phase boundaries and virial coefficients as a function of temperature in K This is a huge negative energy, and rightly so - it is how. These papers also contain further information on equations, such as the validity range. A quick ab-initio calculation of a OCO molecule with bond-length 1.164 Angstroems (quite close to experimental and theoretically deduced length) yields the following Hartree-Fock SCF energy (using the 6-31G basis set): -187.634176090515 Hartrees, which is -492633.5668524824 kJ/mol.
