Liquid Compressibility Values
Bibliography Data
The values of isothermal
compressibility given below
can be used for the
Compressibility value in the
pump setup menu. These
values are given under
athmospheric pressure (X
0
)
and are expressed in Mbar
-1
.
The opposite table refers to
Handbook of Chemistry and
Physics, CRC Press, 60th Ed.
(1979).
