A new correlation for the
viscosity
of
ethylbenzene
is presented.
The
correlation is
based
upon a body
of experimental data that has been critically assessed for internal consistency and for agreement with
theory
. It is applicable
in
the temperature range from
the triple point
to 673
K at
pressures
up to
11
0
MPa
. The overall uncertainty of the
proposed correlation,
estimated
as the combined expanded
uncertainty with a
coverage factor of 2, varies from 1
% for the viscosity at atmospheric pressure
to
5%
for the highest temperatures and pressures of interest.
Tables of the viscosity, generated by the
relevant equations, at selected temperatures and pressures
, and along the saturation
line, are
provided.
Comparison of viscosity of xylene isomers indicated that at very high temperatures the viscosity
correlation of
para
-
xylene has higher uncertainty
than previously postulated. Thus, in this work w
e also
provide a revised viscosity correlation for
p
-xylene.
