Hello,
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 out β is the average between 0 °C and 141 °C, I would be looking for β at 70.5 °C.
Thank you for your help
