Could somebody confirm or negate these Reynolds numbers? The Object is a ethanol still, a twin outlet (Tee fitting) vapor conduit of variable diameters, fed from a boiler which generates the vapor. The vapor speeds are known and correct. I just need clarification of the Re nos relative to pipe diameters.
Thanks in advance

Do you know viscosity of fluid in given positions?

The fluid is ethanol-water vapor assumed to be azeotropic at all points. Azeotrope is 89 mole-% ethanol and 11 mole-% water, or roughly 96% & 4% by volume. Below is the chart I have for properties of the pure (100%) substances...
Many thanks for any input.

With these values for viscosity you can use equation for mixtures at:

And with mixture viscosity, you can calculate Re number using:

above calculator.
