Document Download: AN5-13(2016): Advisory Note No. 5: Industrial Calculation of the Thermodynamic Properties of Seawater

Description

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 development of the formulation is described in detail in a scientific article.

Online calculation

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.

Revision History

• This Advisory Note was adopted by IAPWS in 2013.
• In 2016, minor editorial changes were made to correct the last digits in a few calculated values in Table A1 and to update some references.

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).
