2014.In layman’s terms, viscosity defines a fluid’s resistance to flow. Lienhard V, "Surface tension of seawater," J. This data was correlated with an average absolute percentage deviation between measurements and the correlation of 0.19% and a maximum deviation of 0.60%. The uncertainty of the measurements varied from 0.18 to 0.37 mN/m with the average uncertainty being 0.22 mN/m. They published reference data for the surface tension of seawater over the salinity range of 20 - 131 g/kg and a temperature range of 1 - 92 degC at atmospheric pressure. The surface tension correlation used in this package is based on Nayar et al. The default values are T ds = 25 ☌, S ds = 35 g/kg, and P ds = 0.101325 MPa * T ds, S ds, and P ds are the dead state temperature, salinity, and pressure. Thermal conductivity (pressure dep.)

This software is provided "as is" without warranty of any kind. They will run on all computers that support MATLAB, EES, or VBA. They are a self-contained library and are extremely easy to use. The seawater properties library routines are available in MATLAB, EES, and Excel VBA. Where P 0 is taken as atmospheric pressure (0.101325 MPa) up to 100 ☌ and as the vapor pressure of seawater for higher temperatures. For select functions such as transport and colligative properties, the temperature and salinity also implicitly define the pressure as: For thermodynamic functions, the pressure dependence across 0 - 12 MPa has been incorporated. Some functions are valid only near atmospheric pressures while others are valid for a pressure range of 0 - 12 MPa. The temperature and salinity ranges are 0 - 120 ☌ and 0 - 120 g/kg respectively. They are given as functions of temperature, pressure, and salinity. The properties given by these codes are those needed for design of thermal and membrane desalination processes. This page provides tables and a library of computational routines for the thermophysical properties of seawater.
