Abstract: The present contribution indicates that precisely the same situation - as with the determination of the so-called yield stress of viscoplastic materials - concerns also the value of viscosity describing the initial Newtonian plateau. It is shown that the determination of this value from the experimental data is not unique, significantly subjects to the range of measured parameters, and the proper determination of the precise value is very questionable.
