The osmotic coefficient is an important thermophysical property used to consider the non-ideality of a solvent, such as water. It is usually used to predict the actual osmotic pressure. This chapter presents multicomponent models, correlation, and data used to estimate the osmotic coefficient at different salinity values. Besides, the calculated osmotic coefficient values from the correlations and methods are assessed and compared to the experimental data of seawater. Some correlations and methods are suggested based on their accuracy and operating conditions. In addition, the codes used in this chapter to predict the osmotic coefficient of saline water are supplied.
