The influence of viscosity on the axial mixing of liquid phase was studied in the viscosity range of 0.0008 to 0.014 Pa·s
and the following relation Ped = A Fr1B(v1/vw)c was proposed
where (v1/vw) is defined as viscosity correction factor. The index value C is found to be -0.15 for conditions below the loading point and -0.138 for those within the loading range.
