Steam Tables for Water - Specific Volumes & Enthalpies

[mathis314]

Can anybody post a link for the steam tables of water? Any would work that have specific volumes of the gas and liquid phases at all temperatures, and also have the specific enthalpies of each phase at each temperature.

thanks.

The age of steam tables is over! The age of EES is here!

Seriously, you never have to interpolate in thermodynamics again.

Thanks, Tom!

EES was developed by two professors, Dr. William Beckman and Dr. Sanford Klein, both of the University of Wisconsin. Their experience in teaching mechanical engineering thermodynamics and heat transfer showed that students were spending too much time looking up property information and solving equations for their homework problems, tasks that did not help the students master the subject material.

No kidding!

Instead we should have been learning the correlations and inter-relationships. In grad, my colleagues and I spent a lot of time building property models from scratch.

If you google "saturated steam table", you get thousands of useful hits...

I was introduced to EES but didn't spend much time with it. I'm a little unsure of this issue (sorry about the hijack...). For simple problems, being able to use a table can provide very fast answers. I think like with calculators, they are a good tool, but it is still an open question where the line should be drawn when cutting out unnecessary subjects to teach kids.

That said, I recently found a "table" while doing a problem at work that was form-based: you enter in one property and it gives you the rest. Very slick (sorry, don't have the link on my home comp).

And what about my Psych chart!?

psychometric charts are certainly mad, although they are really useful when calculating humidities.

One of these days I'm going to need a lot of thermodynamic properties for a couple of working fluids, and that will be the day I talk my employer into buying me a copy of RefProp:

For now though, if I need some thermo properties I either look them up in my Thermo book, or the free http://webbook.nist.gov/chemistry/fluid/" .

In my opinion, familiarity with T-S and H-S diagrams (as old-fashioned as they may be) can be very useful in the visualization of power and refrigeration cycles, something that simply looking up single properties using a piece of software wouldn't really help with... Still, it is true that a large chunk of my time in Thermo 1 & 2 was spent looking up properties of air, steam, and R-144a.
