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...
