Dear Freinds,
Can any body have experience in designing the piping at very low Reynold number ( 0.001 to o.1 ) for highly viscous fluid having viscosity 23750 Pa s. I tried hooper 2 K method but it results overestimated pipework .

The viscosity you are working with is well beyond the range normally encountered in fluid mechanics calculations. It is around 50x that of molten glass and processing it would fall more in the realm of extrusions than pipe flow (as understood by chemical engineers). I think you will have more chance of getting good information on one of the plastics forums.

Hi Ashish,
Can you give us indication about the material and process condition ?

Consider this resource , you may contact them to get useful information.
Go to pipe sizing under general engineering in the link and provide the necessary info about your material ( Brix,...)
Good luck.

Sir,
The resource suggested in not giving any full proof method for calculating the pipelines at verry very low Re. Does any one have informations for flow at low Re, Pls share .
Regards

Hi,
In addition to my previous post , consider this document to support your work.
Good luck.

I came across the paper referenced below which deals specifically with high viscosity materials in the sugar industry. The authors also comment that at those very low Reynolds Numbers the Hooper 2K method over estimates the pressure drop.
