Abstract
The viscosities of liquid mixtures of nbutane nhexane and noctane with squalane that represent model mixtures of refrigerants with refrigeration oil were measured at temperatures between 27315 and 33315 K and at pressures from 01 to 30 MPa by using a falling body viscometer The uncertainty of the measurements was estimated to be no larger than 29 The experimental viscosity values were fitted to a Taitlike equation within 28 There are larger deviations between the experimental data and calculated values predicted by the equation of Kanti et al which is derived from the Flory theory By introducing an interaction parameter of the energetic mixing rule into the equation the deviations were significantly reduced
