Heat capacity data for 100% glycerine is reported at many
temperatures (49, 95, 1~.3)
and can be expressed as
Cp(lOO% GLYCERINE) :: 0.535 + 0.00132T
for C p
in Btu/lb.op for T in degrees Centigrade.
(A-16
Substituting
the above value for water and equation A-16 for
100%, glycerine in equation A-1S yields
Cp(SOLN) :: (1.003) (0.063) + 0 .. 937 (0.535+0.00132T)

or
Cp (93.?% GLYCERINE) ... 0.565 + 0.0012LI·T

with an estimated accuracy of ± 3 .. 0 percent.
The heat capacity of Carbopol solutions of approximately
the same concentrations used in this thesis Here reported
by Ferment (63) to be the same as for water.
Ferment
estimated the accuracy of his measurements to be ± 5.0 percent.
Thus the heat capacity of the Carbopol solutions vIas
1.003 ~ 5.0% Btu/lb.Op.
DENSITY
Values of the density, f ' of water at various temperatures
are reported by Badger and McCabe (10).
The data
l,.Jere ass1Lrned to be represented by an equation of the form.
