Sodium chloride is one of the most important substances used in food industry especially as flavour enhancer and as preservative agent. It can be also involved in various other processes including drying, cooling, cryopreservation etc. The proper use of sodium chloride solutions implies a good knowledge of the behaviour of its thermophysical properties such as density, viscosity, heat capacity, entropy etc.
This paper focuses on establishing mathematical correlations between density and viscosity and parameters such as low temperature and concentration. The regression analysis leaded to several equations able to describe the cited properties. The calculated data revealed a high similarity with the existing experimental ones confirming the accuracy of the obtained mathematical models.
The developed equations can be loaded in computer spreadsheet softwares for storing, organizing and manipulating data necessary for industrial and academic users and so facilitating the sizing and optimization calculations of various technological processes and industrial equipments.
