Drop Size Calculation

Reynolds number needs to be  above 5000 to be able to  do the dispersion with a static mixer.

For liquid-liquid systems in turbulent flow the viscosity ratio effects the drop size to a limited extent, as long as the absolute viscosity of the dispersed phase is less than 10 cP and the viscosity ratio does not exceed 10:1. Then...


Note that the DSM is the Sauter Mean drop size, and is dependent on the Mixer diameter, D. The final value of DSM is obtained by multiplying the result of the equation above by the pipe ID.

We is the Weber Number
