Dispersions slurries of up to 45 weight percent water-soluble polymers in nonsolvent carriers were effective for reducing drag in turbulent flowing water streams. Separan or Polyox, in polypropylene glycol, gave about 20 percent friction reduction in mixing times less than 0.3 seconds, and reductions of over 60 percent in 1.5 seconds, in a 0.26-inch i.d. tube. In a 10-inch pipe, friction reductions of 30 percent were obtained. Decreasing the water temperature from 40F to 30F, and adding 3.5 percent salt to the water had only minor effects on friction reduction. The optimum concentration of polymer in water stream was approximately 80 ppm. Dispersions of polymer have been held 18 months without settling or dissolving.
