Abstract
Depending on the concentration, the capillary tube diameter influences two parameters: the apparent viscosity and the critical shear rate for which the transition from steady to unsteady flow regimes occurs. A possible length parameter, characteristic of a given polymer concentration, is defined on the basis of these two parameters.Keywords
