Reducing pipe friction by adding a drag reducing agent has attracted interest as a means to reduce energy consumption.In addition to reducing drag,drag reducing agents should also have a low environmental load and conserve natural resources.However,no drag reducing agent currently satisfies both these conditions.In this study,drag reduction due to nata de coco suspensions with small environmental loading was investigated.The drag reducing effect was evaluated by measuring the pressure drop in circulating pipeline system flow.Nata de coco suspensions reduced drag by up to 25 %,and the drag reduction of nata de coco suspensions was not affected by the mechanical degradation unlike that of typical polymer solutions.
