In this article, based on the results of theoretical and practical studies, local resistances are determined in the zones of narrowing of pneumatic transport air ducts, and the change in air speed is presented in graphical form....

The article presents an analysis of the work done to improve the efficiency of cleaning cotton fiber by heating and the results of experiments to determine the effect of hot air velocity on the change in temperature and humidity of the cotton fiber. As a result, a change in humidity was found from...
