The generalized Reynolds number range covered was 83 to
1286 and the fluid consistency index, evaluated at the
average bulk temperature, ranged from o.ol~_6 to 0.609

Equating the generalized Reynolds number to
the NeHtonian Reynolds number Sh01-JS that the apparent viscosity
used in the above correlation is
1:Jhich is very similar to the apparent viscosi ty in pipes
if N is substituted by V/D.
As reported earlier in this
chapter, Netzner and his co-workers have experimentally
determined that the apparent viscosity in agitated vessels
could best be represented by
