    The quality of mixing depends on the effective energy input by unit mass or unit volume of fluid. It has been found, for example, that the rate of oxygen transfer in aerated fermentors equipped with turbine mixers is nearly proportional to the net mixing power input per unit volume of broth (Hixson and Gaden, 1950).The relationship between mixing power and the type, dimensions and operation
