The electrical noise generated during capillary flow of poly(ethylene oxide) solutions has been studied in detail in mixtures of water and isopropyl alcohol of various solvent powers. The noise level, which increased with flow rate, was found to be an increasing function of the linear dimension of the polymer coils as obtained from intrinsic viscosity data, if the system consists of entangled macromolecules, i.e. if the polymer concentration is higher than the coil overlap concentration.
