Drag-Reduction Properties of Ultra-High-Molecular-Weight Polyacrylamide and Related Polymerse polymers are inexpensive, easy to handle and are extremely effective agents; for example, a 44 percent drag reduction is possible by the addition of 10 parts per million by weight (ppmw) of poly(ethylene oxide) of molecular weight 900,000 (2).
