#EOS               !equation of state specification
FEQ  Helmholtz equation of state for water of Wagner and Pruss (2002).
?LITERATURE REFERENCE \
?Wagner, W. and Pruss, A.,

? Water Substance for General and Scientific Use,"

?The uncertainty in density of the equation of state is 0.0001% at 1 atm
?in the liquid phase, and 0.001% at other liquid states at pressures up
?to 10 MPa and temperatures to 423 K. In the vapor phase, the uncertainty
?is 0.05% or less.  The uncertainties rise at higher temperatures and/or
?pressures, but are generally less than 0.1% in density except at extreme
?conditions.  The uncertainty in pressure in the critical region is 0.1%.
?The uncertainty of the speed of sound is 0.15% in the vapor and 0.1% or
?less in the liquid, and increases near the critical region and at high
?temperatures and pressures.  The uncertainty in isobaric heat capacity
?is 0.2% in the vapor and 0.1% in the liquid, with increasing values in
?the critical region and at high pressures.  The uncertainties of
?saturation conditions are 0.025% in vapor pressure, 0.0025% in
?saturated liquid density, and 0.1% in saturated vapor density.  The
?uncertainties in the saturated densities increase substantially as the
?critical region is approached.
