Experimental results of drag reduction using microgel type and linear type of Na-polyacrylate are described. The microgel type showed no drag reduction effects andsuppressed the drag reduction effects of the linear type. This indicates that elastic corn-ponents in the fluid dose not necessarily have the drag reduction effect. Dependenciesof drag reduction effect of the linear type on salt concentration and pH indicated thatmore extended conformation of polymer induces more drag reduction effect.[drag reduction effect, turbulence, polyion, microgel, elastic component in the ]l fluidl
