Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am currently looking at a way to calculate brine density using temperature, pressure and salinity.

I found the following page which describes the change in fluid density with pressure and temperature :

http://www.engineeringtoolbox.com/fluid-density-temperature-pressure-d_309.html

However I am missing two parameters which I haven't been able to find for brines:

-β = volumetric temperature expansion coefficient (m3/m3 oC)

-E = bulk modulus fluid elasticity (N/m2)

Ideally I would need to find an equation which takes in pressure, temperature and salinity which are my known variables. Or tables, the salinity of my brine is 7 wt%, the pressure around 400 bars and the temperature of 141 °C . Note: Since the temperature used to work outβis the average between 0 °C and 141 °C, I would be looking forat 70.5 °Cβ.

Thank you for your help
