Measurement of isobaric heat capacity of R125.
Author(s) : KAGAWA N., MATSUGUCHI A., WATANABE K.
Summary
The specific isobaric heat capacity (cp) was measured for R125 (pentafluoroethane) in the gas phase. Twelve measurements for R125 were obtained at temperatures from 313 to 333 K and at pressures from 0.8 to 2.4 MPa. Some of them are close to the saturation curve. The expanded uncertainty (k=2) of the temperature measurements is estimated to be less 23 mK, and that of the pressure measurements is less 14 kPa. The expanded uncertainty for cp is estimated to range from 12 to 22 J/kg.K. Also, the experimental data were compared with available equations of state.
