The effect of polymer concentration on drag reduction was studied experimentally with dilute distilled water solutions of a polyacrylamide and a polyethyleneoxide, molecular weights 4.7 and 1.3 x 1 OB respectively, in a 0~94.5 cm i.d. pipe. During drag reduction the polymer solutions obeyed friction
