This Advisory Note presents recommendations for calculating the thermodynamic properties of seawater for "industrial use". The Advisory Note states that it is acceptable to calculate thermodynamic properties of seawater using the IAPWS-IF97 formulation for industrial use for pure water in cases where one would be using IAPWS-IF97 for pure water properties elsewhere in the calculations (for example, seawater cooling of a power plant).
The Russian National Committee of IAPWS (through Moscow Power Engineering Institute) has provided an online calculation page, which may be useful in program development and verification. Note that IAPWS is not responsible for the content of these online calculation pages.
This Advisory Note is the product of the Working Groups "Thermophysical Properties of Water and Steam" (TPWS) and "Industrial Requirements and Solutions" (IRS) and the Subcommittee on Seawater (SCSW) of the International Association for the Properties of Water and Steam (IAPWS).
