“…N o regard was taken in the preparation of Figure 4 of the data recorded in Table I1 in estimating the effects of pressure upon the viscosity of n-decane in the gas phase. The influence of pressure was established by application of the quasitheoretical corrections recommended by Galloway (7,8) to the data. However, within the constraints of such correc- Table I1 were employed to establish the lines shown in Figure 4.…”

The viscosity of n-decane was measured at temperatures between 220' and 400' F. in the gas phase at pressures well below the vapor pressure. The viscosity of ndecane in the liquid phase was measured at pressures as high as 5000 p.s.i. in the temperature interval between 40' and 400'F. Good agreement with other investigators was obtained for the liquid phase, and reasonable agreement with the prediction of the viscosity of n-decane gas at attenuation by statistical mechanical considerations. The data are presented in graphical and tabular form.

“…Residual thermal conductivity as used in this investigation represents the difference between the thermal conductivity at attenuation and that at the state in question for the same temperature. Attenuation is designated as that state at which the fluid can be considered as continuous in nature, and yet the deviation from zero pressure is sufficiently small that simple assumptions may be used to predict the thermal conductivity of many molecules from statistical-mechanical considerations (13,14). Residual thermal conductivity is often known as a "thermal conductivity excess."…”

“…A few measurements in the liquid phase are available at pressures near that of the atmosphere (4, 40,41). Some progress has been made in predicting the thermal conductivity of the lighter paraffin hydrocarbons at attenuation (14,21,36,42). However, it has not been found feasible to predict behavior at pressures markedly in excess of atmospheric.…”

For the calculation of the ideal dynamic ~iscosity ~]Ideal (T) and the ideal thermal conductivity A~dea~ (T) the critical temperature Tkr, the critical specific volume Vkr , the molecular mass M, the "critical parameter" ~kr and the molar isoehoric heat capacity ~v(T) is needed. Not only the theoretically determined but also the empirically determined ,,extended correspondence law" gives for practical use a good representation of the measured data, which for the "associating substances" and the "quantum substances" is not so good as for the "normal substances".
