Cstr mass transfer
Webmass transfer is dominating and the volumetric mass transfer coefficient is approximated by kLa. The K La depends on numerous parameters, including liquid phase properties, reactor geometry and operating conditions. The volumetric mass transfer coefficient kLa is a critical parameter in the design of reactors and aeration systems. During the ... http://cr.colostate.edu/transtream.html
