In this paper. we present a novel method we have developed for measuring the drag reduction in a dilute polymer solution. based on the triboelectricity phenomenon. The presence of a small quantity of polymer with high molecular density in a liquid decreases the friction of the liquid on solid walls. https://mysocialfeeder.com/story4381126/defining-human-rights-in-times-of-covid-human-rights-discourse-in-the-uk-and-devolved-legislatures
