Abstract
The aqueous solution of ammonia has been used not only for refrigeration cycle but also for waste heat recovery power systems and other purposes. Thus, the thermodynamic and transport properties of NH_3-H_2O mixtures over a wide range of state parameters are needed. Authors measured the pVTx properties of this substance and found out the behavior of the maximum densities for the aqueous solution of ammonia. This paper describes the behavior and correlation of the maximum density equation of NH_3-H_2O mixtures based on the experimental data.
