No chemical exists that has non been submitted to a mixing process during its synthesis. Furthermore, stirring is important for the pharmaceutical and food industries, too.The most important mixing operations are applied to homogenize miscible liquids, to intensify the heat transfer between a liquid and the heat exchanger, and to perform mass transfer in multiphase systems, to whirl up solid particles in fluids and to disperse immiscible liquids.This book discusses in detail the above listed operations, tak 606 $aMixing 606 $aMixing machinery 615 0$aMixing. 615 0$aMixing machinery. 676 $a660.284292 700 $aZlokarnik$b Marko$f1931-$022266 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830761003321 996 $aStirring$93934116 997 $aUNINA
