Thermodynamics Tables for Reference

Click For Summary

Discussion Overview

The discussion revolves around recommendations for thermodynamics tables, specifically seeking resources that are available in metric or both metric and British systems. Participants share their preferences for physical books versus online resources and discuss the costs associated with various tables.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Meta-discussion

Main Points Raised

  • One participant requests recommendations for thermodynamics tables, expressing a preference for physical books over digital formats.
  • Another participant suggests the JANAF Tables and the International Critical Tables as potential resources.
  • It is noted that many thermodynamics tables, particularly steam tables, are available online for free from standards organizations like NIST.
  • A participant mentions the high cost of the JANAF Thermochemical Tables, indicating a budget constraint.
  • There is a discussion about the relevance of older editions of thermodynamics tables, with one participant suggesting that the thermo properties of substances remain consistent for engineering purposes despite the age of the tables.
  • One participant shares their experience with older editions of steam tables used during their education, highlighting the importance of organizations like IAPWS in maintaining updated formulations for thermodynamic properties.
  • A participant confirms they downloaded the JANAF tables from the NIST website, following the suggestion from another participant.

Areas of Agreement / Disagreement

Participants express differing views on the preference for physical books versus online resources, and there is no consensus on the best resource due to varying budget considerations and personal preferences.

Contextual Notes

Some participants mention the potential obsolescence of older editions of thermodynamic tables, but do not reach a definitive conclusion on their applicability. The discussion reflects a range of experiences and preferences regarding the use of thermodynamic tables.

Does anyone know of a thermodynamics tables for reference to recommend me?... It would be preferable in metric system or in both, british and metric. I searched in the past posts and, I didn't find information about this issue.

I found this tables on Amazon, but I prefer to hear from your advice:

I lost the one I had, don't know where.

Thank you in advance

You can find a lot of this information, particularly steam tables, already on the web. I wouldn't buy a paper book unless you needed to stuff something else in your backpack.
Standards organizations, like the NIST, publish these tables which can be downloaded.

Thank you very much for your messages. Despite the fact I am an old school person, so I prefer to read from a book more than from a computer, I found the JANAF Thermochemical Tables really expensive for my budget ($ 400 or higher)... so, I will follow your suggestion, SteamKing, and I will use the NIST tables.

I assume the older editions (more affordable) of this book are out dated.

Thank you again

Well, steam is steam and R-12 is R-12. The thermo properties of each substance should be the same for engineering purposes, regardless of the age of the work.

When I was in college, the required texts for my marine engineering courses included the 1967 edition of the ASME Steam Tables (which was a pretty sizable hardcover tome) and the 1944 edition of the Keenan-Keyes steam tables (all in chart form), which was a very slender book. I believe the ASME work included a folded Mollier chart for steam which I used to plot steam turbine state lines.

There is a whole international organization called the IAPWS which develops various formulations to calculate the properties of water which are tabulated in the steam tables. Organizations like NIST and ASME work with the IAPWS to make sure all their data line up with the latest formulations. Since a lot of calculations requiring thermo properties of water are done on computer nowadays, there is a need to use for formulas which can be evaluated, given inputs like pressure and temperature, and have a routine calculate enthalpy and entropy and what not.

Thank you very much for your valuable information. By the way, I downloaded the JANAF tables from the NIST website, as you indicated.
Thank you again.
