Studying the effect of chitosan as drag reducing agent in water flowing systems with different concentration and preparation using different acid types

The investigation of turbulent drag reduction, which is caused by the addition of a small amount of polymer or some other substances to the liquids flowing systems has been the focus of attention of many scientists for the last decades. Due to the reduction of the drag, pumping power for the pipelin...
