**SES36**

SES36 provides approximate thermodynamic properties for the mixture of R365mfc (1,1,1,3,3-pentafluorobutane) and perfluoropolyether, which has the trade name of SES36. This mixture is treated as a pseudo-pure fluid with a molar mass of 184.85 g/mol. Only thermodynamic property data are available and they are based on the equation of state in:

The correlation is valid for temperatures in the range between 200 K to 1500 K for pressures less than 50 MPa.

Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K, respectively, for saturated liquid at 0°C.

Note that there are several typographical errors in the paper.

Coefficient n_11 in Table 1 should be 2.46053

Equation 1.3 should have b_2*tau in the expornential term.

b_2 should be 2197 K

Transport properties and surface tension are derived fromb data reported by:
