Sutherland constant

Table VIII.1 shows some of the experimental values that have been obtained for viscosity coefficients and Sutherland constants. It should be...

However, this equation is an approximation with respect to intra-molecular interactions, a more exact relation t] = 0A99 mVl is obtained. Viscosity is independent of pressure but increases with increasing temperature because of rising molecule speed. The temperature dependence of viscosity is described by an empirical expression the C Sutherland constant and the constant B follow from Eq. (4.42) ... 

For the data in Table 18 the dissociation energies of the primary valence bond, i.e. the heats of combustion had to be used, but now we must consider the energy of overcoming molecular cohesion, which is measured by the heats of sublimation and vaporization or by the van der Waals constant a. For the latter, and for the Sutherland constant closely allied to it, van Laar has already established certain additive relationships. These are expressed even more definitely in the well known Traube rule for the heats of adsorption of homologous series, which, according to Eucken, are closely related to the heats of vaporization.

In this last formula u should be expressed in m/hr. We shall take the thermal conductivity of the combustion products to be equal to the thermal conductivity of air and find its value according to the Sutherland formula with the constants A0 = 0.0192kcal/hr m deg, C = 125 deg (MacAdams). At high temperature... 

The theory that liquid water is a mixture of polymerised water molecules, or contains dissolved ice, apparently first suggested by Rowland and by Whiting,2 was independently put forward by J. J. Thomson,3 Rontgen, and Sutherland.3 The ice molecule is supposed to be more complex than the liquid but less dense. This theory has been supported by appeal to the very abnormal properties of liquid water (high surface tension and dielectric constant, great ionising power for solutes, high b.p. as compared with expansion on...
