Information

Calculation of fluid properties for the mixture common molten salt (60% NaNO3 and 40% KNO3) in the fluid region of 573.15 to 873.15 Kelvin.The use of this molten salt is usally used in solar thermal system due to its high thermal capacity and the high range of temperature.

This package of thermodynamic properties is explicit for pressure and specific enthalpy, however it is based in functions where the dependency is exclusively in the temperature.

Restriction

The functions provided by this package shall be used inside of the restricted limits according to the referenced literature.
