Python implementation of standards from The InternationalAssociation for the Properties of Water and Steam
Python implementation of standard from IAPWS (http://www.iapws.org/release.html). The module implements the full set of standards, including:
IAPWS-IF97 IAPWS-95 IAPWS-06 for Ice IAPWS-08 for seawater IAPWS-05 for Heavy water ...
In debian you can find in official repositories in jessie, testing and sid. In ubuntu it’s in official repositories from ubuntu saucy (13.10). In other system you can install using pip:
pip install iapws
or directly cloning the github repository:
git clone https://github.com/jjgomera/iapws.git
and adding the folder to a python path. This is the recommended option to have the latest version.

For a rapid usage demostration, see this examples
from iapws import IAPWS97 sat_steam=IAPWS97(P=1,x=1) #saturated steam with known P sat_liquid=IAPWS97(T=370, x=0) #saturated liquid with known T steam=IAPWS97(P=2.5, T=500) #steam with known P and T print(sat_steam.h, sat_liquid.h, steam.h) #calculated enthalpies
from iapws import IAPWS95 sat_steam=IAPWS95(P=1,x=1) #saturated steam with known P sat_liquid=IAPWS95(T=370, x=0) #saturated liquid with known T steam=IAPWS95(P=2.5, T=500) #steam with known P and T print(sat_steam.h, sat_liquid.h, steam.h) #calculated enthalpies
IAPWS-05 for Heavy water
from iapws import D2O sat_liquid=D2O(T=370, x=0) #saturated liquid with known T print(sat_liquid.h) #calculated enthalpy
IAPWS-06 for Ice Ih
from iapws import _Ice ice=_Ice(273.15, 0.101325) #Ice at normal melting point print(ice["rho"]) #Calculated density
IAPWS-08 for seawater
from iapws import SeaWater state = SeaWater(T=300, P=0.101325, S=0.001) #Seawater with 0.1% Salinity print(state.cp) # Get cp
I’ve tried to test all code and use all values for computer verification the standards give, but anyway the code can have hidden problem. For any suggestions, comments, bugs … you can usage the github issue section, or contact directly with me at email.
