n The ratio of the kinematic viscosity of a specified solution of the polymer to the kinematic viscosity of the pure solvent. This can also be written as the ratio of the viscosities of pure solvent ( η solv) and a solute in solution ( η sol) at a concentration according to the method of calculating the Staudinder Index [ η]:
$$\eta _{{\rm sol}} /\eta _{{\rm solv}} = \eta _{{\rm rel}} $$
