How to calculate Reynold's number for rheology of low viscous fluid in coaxial geometry (steady-state rheology) ?

I have varied the shear rate from 1s-1 to 500 s-1 and wish to study the change in Reynold's number for a juice with 18% solid concentration. How to calculate the velocity term? or can it be...
