The absolute viscosity calculated from the formula(where p = the pressure, t the time, r the radius, l the length of capillary, and v the volume of liquid), which connects the viscosity of a liquid with the rate of flow through a long capillary tube, is not often made use of, mainly on account of the difficulty of accurately determining some of the constants (r in particular).

The absolute viscosity at atmospheric pressure was determined experimentally for the vapour phase of two halogenated hydrocarbon compounds, refrigerants R12 (CCl2F2) and R22 (CHCl2F) in the general temperature range −39·7° to 91·8°C. The maximum error of the data is believed to be ±3 per cent. Comparison with previous secondary measurements on the same compounds reveals that the maximum deviation of previous measurements are +5 per cent and −6 per cent for R12 and R22, respectively, over the common temperature range. The data obtained in this work and by others were correlated using third and fourth degree polynomials, a power function of the absolute temperature, and a collision theory approach, which yielded values for the reduced dipole energy, the velocity collision diameter, and the maximum energy of attraction for the molecules. Comparison of the data with that predicted by simple kinetic theory has been made.

The line denoting variation of the absolute viscosity of mercury with temperature is incorrect. It should be replaced by a line (straight within the limits of the diagram) joining the points: o°, 16-8 millipoise 40°, 14*5 millipoise (iii) p. 52, second paragraph. The first phrase should be ignored, although it is true for the kinematic viscosity of mercury.
