The viscosity increment for ellipsoids of revolution. Some observations on the Simha formula.
Outstanding uncertainties in the widely employed Simha (J. Phys. Chem. 44 (1940) 25) function for the viscosity increment r of macromolecules as modelled by axially symmetric ellipsoids are resolved. A simple development of the analysis also reveals an interesting relationship between nu and the translational frictional property of macromolecules.
