A 3.18-cm-ID smooth turbulent flow pipe facility was utilized to measure the drag-reduction characteristics of three polymer solutions Polyox WSR-301, Separan 237, and Magnifloc 835A. A rotating disk was used to degrade the polymer solutions, and accurate control was maintained over the energy used to agitate shear degrade them. Quantitative data were obtained on the relationship between degradation and drag reduction for these three polymers and for blended solutions prepared by mixing two different polymers in various proportions.
