Water - Properties at Gas-Liquid Equilibrium Conditions

Comprehensive thermophysical properties of water and steam at equilibrium conditions (saturation). Includes density, viscosity, enthalpy, entropy, specific heat, Prandtl number, thermal conductivity, and thermal diffusivity as a function of temperature from the triple point to the critical point. Data provided in both SI and Imperial units.
