Enthalpy-Temperature Tables for Water

Enthalpy-Temperature Tables for Water

(OP)
Hi all,

I need to make an enthalpy-temperature plot for water. I originally thought this meant looking up enthalpy vs. temperature changes at specific constant pressures for water online but I couldn't find such tables.

I was wondering if anyone has any sources or databases that could provide such information, or if I happen to be going in the completely wrong direction and should be using steam tables instead. However, I don't see how using steam tables will allow me to get the relationship between enthalpy and temperature at constant pressures.

Thanks in advance!

If you manage to put your hands on it, the software EES (Engineering Equation Solver) can help you.

NIST Database is an excellent resource for component properties:

http://webbook.nist.gov/chemistry/form-ser.html

For liquid water, type H2O in the search box and tick "Condensed phase" under Thermodynamic Data. Then click the search button and you'll be taken to the main H2O page. You can then choose either "Condensed phase thermochemistry data" or "Fluid properties" link. After you define the range of T or P values you will obtain table or chart for the desired properties, i.e.:
