Notes:
The turbulent drag reduction characteristics of the rod-like polysaccharide xanthan gum dissolved in water was investigated using a rotating disk apparatus. The ultrasonic degradation method was adopted to obtain polymer fractions of different molecular weights of xanthan gum for this study. The drag reduction curve was then plotted to observed the universal characteristics of xanthan gum, and the intrinsic concentration was found to be an extremely useful quantity in normalizing the drag reduction data for different molecular weights.
