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.
Steam tools iPhone app. Simple to use, the iPhone app enables quick and easy access to both our Steam Table and Saturated Steam Pipe Sizing tools without the need for an internet connection, making it perfect for steam engineers on the go. Density steam, dynamic viscosity steam, kinematic viscosity steam, specific inner energy steam, specific enthalpy steam, specific entropy steam, specific isobar.

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) |
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.
