Brine Density

Volumetric properties database
A large number of studies of volumetric properties of sodium chloride
brines have been published over the last 80 years. Published data have
included specific volume, relative volume, compressibility, density, and
the difference in density between that of brine and pure water.
Spivey et al. compiled a database of published data on volumetric
properties of sodium chloride brines for temperatures from 32ºF
to 530ºF (0ºC to 277ºC), pressures from 14.5 to 29,000 psia (0.1 to
200 MPa), and salinities from 0% to 26% sodium chloride by weight
(0 to 6 g-mol/kg H 2 O). 1 They then used this database to develop a new
correlation for estimating brine density, specific volume, and coefficient
of isothermal compressibility.
