What is "Cuprammonium Fluidity" - Definition & Explanation

The reciprocal of the dynamic viscosity of a solution of cellulose of prescribed concentration in a cuprammonium solvent of prescribed composition, measure under precisely defined conditions.

NOTE:

These solutions commonly exhibit non-Newtonian flow behaviour. Cuprammonium fluidity does not therefore have absolute physical significance as does the fluidity of a Newtonian liquid, although it has hitherto been expressed in reciprocal poises. It is considered that it should be regarded as an empirical quantity and because of this, the results are given in units of cuprammonium fluidity and are not linked to a specific unit.
