Seawater Properties: 40
Thermophysical properties of seawater as a function of temperature (0-40 degC) and salinity (0-40 PSU) at atmospheric pressure. Properties include density, dynamic viscosity, kinematic viscosity, thermal conductivity, specific heat, speed of sound, vapor pressure, surface tension, and electrical conductivity. Based on IAPWS-2008 seawater formulation and Sharqawy et al. (2010) correlations. Distinct from the fluid_properties table which stores only a single seawater reference point. Covers salinities from pure water (0 PSU) to hypersaline (40 PSU) including standard seawater (35 PSU per ITTC 1963).
