Mass transfer performance of curve blade impeller in gas-liquid mixing

In this work the volumetric mass transfer coefficient, k a of a six bladed curve blade impeller 6CB was compared with a standard six bladed Rushton Turbine (6RT) by measuring dissolved oxygen content in 20cm diameter cylindrical tank. It was found that for gas rated in between 15liter/min and rpm in...
