چکیده انگلیسی
The density and viscosity of propylene glycol have been simultaneously measured over the temperature range from (298-452) K and at pressures up to 245 MPa using a combined method of hydrostatic weighing and falling-body techniques, respectively. The combined expanded uncertainty of the density, pressure, temperature, and viscosity measurements at the 95% confidence level with a coverage factor of k = 2 is estimated to be (0.15-0.30) %, 0.05%, 0.02 K, and (1.5-2.0) %, respectively. The measured high-temperature and high-pressure PVT data for propylene glycol were used to develop theoretically based Tait-type equation of state (EOS). The measured viscosities were used to develop theoretically based viscosity correlation models (Arrhenius-Andrade and VFT type models) with the pressure dependent parameters.
