R1225ye(Z)

 

R1225ye(Z) provides approximate thermodynamic property data for cis-1,2,3,3,3-Pentafluoroprop-1-ene, MW 132.03 g/gmole, CAS# 5528-43-8).  The thermodynamic properties are provided using the Martin-Hou equation of state (A.I.Ch.E. Journal, 1:142, 1955) as fitted by:

"Saturated pressure measurements of cispentafluoroprop-1-ene (R1225ye(Z))"

Int. J. of Refrigeration, Vol. 69, (2016), pp. 243-250

 

The properties are provided for temperatures between 240 K and 450 K for pressures up to 10 MPa.

 

The IIR reference is used for specfic enthalpy and entropy, i.e., h=200 kJ/kg and s=1 kJ/kg-K for saturated liquid at 273.15 K.

 

Transport properties are estimated for temperatures between 240 K and 380 K based using a corresponding states approach as suggested in:
