!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.

?Estimated uncertainty for viscosity over full region of validity is <10%, except
? near the critical region where deviations can be much larger.

?VISCOSITY
? The ECS parameters for viscosity were based on the data of:
? Avelino et al. J. Chem. Eng. Data, 51:1672-1677, 2006.
? Ripple, D. and Defibaugh, D., "Viscosity of the Saturated Liquid Phase of Three Fluorinated Ethanes: R152a, R143a, and R125," J. Chem. Eng. Data, 42:360-364, 1997.
? Average absolute deviations of the fit from the experimental data are:
? Avelino: 0.4%; Ripple: 1.2%
?
?Estimated uncertainty for viscosity over full region of validity is <10%
?
?The Lennard-Jones parameters were obtained by fitting gas phase viscosity data of Takahashi et al., Int. J. Thermophys., 20:435-443, 1999, and Wang et al., J. Eng. Thermophys., 30(4):1455-1458, 2009.
