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 PropertyUnits
hspecific enthalpykJ/kg
Ppressurebar = 0.1 MPa
PrPrandtl number (= ηCp/λ)dimensionless
rspecific enthalpy of vaporizationkJ/kg
sspecific entropykJ/(kg K)
tstemperature at saturation 
uspecific internal energykJ/kg
νspecific volumem3/kg
εstatic dielectric constantdimensionless
ηviscosity10−6 kg/(s m) = MPa s
λthermal conductivitymW/(K m)
ρdensitykg/m3
σsurface 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.
