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

We is the Weber Number
