Tables B-1 and B-2 present data for saturated liquid and saturated vapor. Table B-1 is presented information at regular intervals of temperature while Table B-2 is presented at regular intervals of pressure. Table B-3 presents data for superheated vapor over a matrix of temperatures and pressures.
The figures and tables below shows how water enthalpy and entropy changes with temperature (°C and °F) at water saturation pressure (which for practicle use, gives the same result as atmospheric pressure at temperatures < 100 °C (212°F)). See Water and Heavy Water - thermodynamic properties.
These tables are created using the NIST Steam Tables. Please see the link: http://www.nist.gov/srd/upload/NISTIR5078.htm (referred on 2014.02.06). The reader should refer to the NIST Steam Tables for original data. The original tabulation, created by, National Institute of Standards and Technol-
The thermodynamic property table and the graphs for water below is based on the industrial formulation by IAPWS-IF97. This site also contains a calculator capable of calculating the properties as function of temperature and pressure.
Steam tables contain specific volume, enthalpy, internal energy, and entropy of water (both liquid and vapor) over a range of temperatures and pressures, including at saturation and supercritical conditions.
This calculator calculates thermodynamic properties for water as function of pressure and temperature. It is capable of calculating the properties density, specific isobaric heat capacity, specific isochoric heat capacity, specific enthalpy, specific entropy, specific internal energy, dynamic viscosity and kinematic viscosity as function of ...
