# STEAM TABLES

The following tables of the properties of steam are taken directly from Chapter 5.5.3 of the Heat Exchanger Design Handbook, 1986, by C. F. Beaton.

The tables in this section are reprinted, with permission, from NBS/NRC Steam Tables.

### Symbols and Nomenclature for the Tables

 Symbol Property Units h specific enthalpy kJ/kg P pressure bar = 0.1 MPa Pr Prandtl number (= ηCp/λ) dimensionless r specific enthalpy of vaporization kJ/kg s specific entropy kJ/(kg K) ts temperature at saturation u specific internal energy kJ/kg ν specific volume m3/kg ε static dielectric constant dimensionless η viscosity 10−6 kg/(s m) = MPa s λ thermal conductivity mW/(K m) ρ density kg/m3 σ surface tension kg/s2 = N/m specific entropy of vaporization kJ/(kg K)

### Subscripts

 g denotes a saturated vapor state l denotes a saturated liquid state

The reference state for all property values is the liquid at the triple point, for which state the specific internal energy and the specific entropy have been set to zero. Figure 1. Viscosity. Figure 2. Thermal conductivity. Figure 3. Prandtl number.
