The problems of mathematical modelling the load torques on shaft of driving motor designed for applications in polymerization reactors are presented in the paper. The real load of polymerization drive is determined as a function of angular velocity. Mentioned function results from friction in roll-formed slide bearing as well as from friction of ethylene molecules with mixer arms in p... https://www.bekindtopets.com/quick-offer-Kansas-City-Chiefs-2-Piece-Stemless-Wine-Glass-Set-with-Collectible-Box-must-buy/
