Physical Chemistry for the Biosciences
Because the presence of solute molecules normally disturbs the streamline flow
of liquids, thus causing an increase in viscosity, rjTe] is usually greater than unity.
Additional definitions of viscosity follow: Specific viscosity: ^sp = rjlel - 1 (16.20) ...

... encountered in biochemistry. Figure 7.3. Measurement of intrinsic viscosity.
Specific viscosity is measured at a range of concentrations of macromolecule/
particle. Intrinsic viscosity ([n]) is the specific viscosity (nsp) at a concentration of
zero.

Food Proteins and Their Applications
Table 3 shows the effect of heat on specific viscosity of WPI solutions at two
different heating conditions [39]. At 70°C, the viscosity of a 5% WPI solution
increases with heating time; however, the increase was only about twofold after
20-minute ...

Encyclopedia of Chromatography
The specific viscosity rjsp = r\r — 1 is the fractional increase in viscosity between
the solution and solvent. The effect of the concentration can be normalized by
division of rjsp by the concentration C, expressed in grams per deciliter (g/dL).
Calculate the specific viscosity, T1sp, of each Sample Solution by the formula
and then calculate the reduced viscosity of each by the formula Plot the reduced
viscosity of each solution against concentration, and extrapolate to zero ...

Viscosity of Liquids: Theory, Estimation, Experiment, and Data
A full description of the instrument is given by Stillman19. It is also used for
determination of specific viscosity of tars and their fluid products according to
ASTM D1665-98 standard. The constructional features of the viscometer are
shown in Fig.

Introduction to Food Chemistry
The specific viscosity is the fractional relative viscosity expressed in proportion to
the solvent. Adjusting the specific viscosity for concentration gives reduced
viscosity. To determine intrinsic viscosity draw a graph of rjre^ versus
concentration ...
