Equation of state for HFC-134a.
Implements the equation of state given in: R. Tillner-Roth and H.D. Baehr. "An International Standard Formulation for The Thermodynamic Properties of 1,1,1,2-Tetrafluoroethane (HFC-134a) for Temperatures From 170 K to 455 K and Pressures up to 70 MPa". J. Phys. Chem. Ref. Data, Vol. 23, No. 5, 1994. pp. 657–729. http://dx.doi.org/10.1063/1.555958
Definition at line 16 of file HFC134a.h.
Pressure [Pa].
If two phases are present, return the saturation pressure; otherwise return the pressure computed directly from the underlying eos.
Definition at line 70 of file Sub.cpp.
The derivative of the saturation pressure with respect to temperature.
Definition at line 80 of file Sub.cpp.
Saturation temperature at pressure p.
Definition at line 125 of file Sub.cpp.
Vapor fraction.
If T >= Tcrit, 0 is returned for v < Vcrit, and 1 is returned if v > Vcrit.
Definition at line 104 of file Sub.cpp.
true if a liquid/vapor mixture, false otherwise
