coat-hanger die

Hi guys;
Well my problem is coat hanger die. Does anybody knows flow rate per
width(q) and die land relationship for newtonian and non-newtonian
fluids?
Or can you offer me book or publication?
And also in a single screw extruder, How can velocity and rate profile
be related for fluids show slippage?
I need an equation for that too.
Thanks a lot.
Regards...

Michaeli had a book out on extrusion die that was helpful in this regards IIRC. The exact title escapes me as my copy has disappeared over the years.
I'm not aware of any slip-in-the-extruder equation. It could be pretty hairy as slip depends on wall shear which would be nonconstant down the barrel.
