!The fluid files contain general information about the fluid in the first 15 to 20 lines, followed by sections for the
|
||||
! equations of state, transport equations, and auxiliary equations. Equations of state are listed first. The NIST recommended
|
||||
! equations begin with a hash mark (#). The secondary equations begin with the @ symbol. These symbols can be swapped to
|
||||
! select a secondary equation as primary and the primary as secondary. The equation of state section also contains auxiliary
|
||||
! equations for the ideal gas heat capacity or ideal gas Helmholtz energy. Below the equations of state (both primary and
|
||||
! secondary) are the transport equations, first viscosity and then thermal conductivity. These are then followed by the
|
||||
! secondary equations if available. The transport section also contains auxiliary equations required to calculate either the
|
||||
! dilute gas state or the critical enhancement. At the end of the file are additional but not necessary auxiliary equations,
|
||||
! including simple equations for the vapor pressure, saturated liquid and vapor densities, melting line (for some fluids), and
|
||||
! sublimation line (for even fewer fluids). This section also contains the equations for dielectric constant and surface
|
||||
! tension if available. The sections are divided by different symbols (these being _-+=^*~) to aid the eye in locating a
|
||||
! particular section. Secondary equations are indented 10 spaces to avoid confusion with the NIST recommended equations. The
|
||||
! end of the fluid file is marked with @END. Anything below that is ignored.

?The uncertainty in density of the equation of state is 0.02% from the
|
||||
? triple point up to temperatures of 523 K and pressures up to 12 MPa and
|
||||
? from temperatures of 240 to 523 K at pressures less than 30 MPa. In the
|
||||
? range from 270 to 350 K at pressures less than 12 MPa, the uncertainty
|
||||
? in density is 0.01%. The uncertainty at very high pressures (>1 GPa) is
|
||||
? 0.6% in density. The uncertainty in pressure in the critical region is
|
||||
? estimated to be 0.02%. In the gaseous and supercritical region, the
|
||||
? speed of sound can be calculated with a typical uncertainty of 0.005% to
|
||||
? 0.1%. At liquid states and at high pressures, the uncertainty increases
|
||||
? to 0.5% - 1.5%. For pressures up to 30 MPa, the estimated uncertainty
|
||||
? for heat capacities ranges from 0.3% at gaseous and gas like supercritical
|
||||
? states up to 0.8% at liquid states and at certain gaseous and supercritical
|
||||
? states at low temperatures. The uncertainty is 2% for pressures up to
|
||||
? 200 MPa and larger at higher pressures. The estimated uncertainties of
|
||||
? vapor pressure, saturated liquid density, and saturated vapor density
|
||||
? are in general 0.02% for each property. The formulation yields a
|
||||
? reasonable extrapolation behavior up to the limits of chemical stability

? of nitrogen.
