!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 equation of state is valid from the triple point to 750 K with
? pressures to 200 MPa, although the uncertainties increase substantially
? above 100 MPa. The uncertainties in density are typically 0.2% below 100
? MPa, increasing to 1% at pressures up to 200 MPa. The uncertainty in vapor
? pressure is 0.2% and the uncertainties in speed of sound are 0.01% in the
? vapor phase (including supercritical conditions) at low pressures, 1% below
? 20 MPa in the liquid phase, and 3% below 100 MPa at other state points.
? The limited amount of heat capacity data show that the uncertainty is 1%
? near the triple point, and uncertainties in heat capacities at other states
? are probably within 2%, at least at pressures up to 20 MPa.
