Steam Table Metric Units

Recommended Posts

I was thinking of buying one on amazon this metric steam table by Keenan and Keyes. Its $82.5. 

But was thinking about if its going to be worth it just for the purpose of using in the exam? 

I have a Metric steam tables but the Sat. Temperatures only go up to 373celcius, Sat. Pressure only up to 22MPA, the superheat is pretty good though its up to 1000MPA.

The saturated tables don’t go beyond 373.95C and 22064 kPa because that is the critical point.

Oh yes, did the conversion, its the same. The one I downloaded should suffice. Thanks!

Here are your best bets for both standard and SI unit steam tables (both free):

Here is a link for the best Imperial units table I could find (I did a lot of searching) http://www.tuner.tw/omega%20cd/zsection/STEAM_TA.PDF  and a GREAT compilation of SI units (tables 1, 2, and 3) here: https://www.nist.gov/sites/default/files/documents/srd/NISTIR5078.htm

Thank you! This is good!

One note about the SI tables from NIST (and the MERM): the specific volumes given are in units of cm^3/g and these are only shown on the first page, whereas some other references and most of your calculations will likely be in m^3/kg. I wasn't smart enough to catch that the first time around on some problems while rushing through. I just hope I can spare someone else a headache!

Thanks for the heads up! Marked every page of the steam table so I won't miss! haha

You ALWAYS have to be mindful of units. ALWAYS.  And when you think you were, check again.

Quick update on this. The link for the USCS units is no longer working, but I found the same table that used to lead to, here: https://www.bbpsales.com/wp-content/uploads/2017/01/3A-Appendix-Steam-Tables.pdf

The link provided by @Audi driver, P.E. for the SI tables from NIST is still functional (but it wasn't during the recent government shutdown).

The moral of the story is download them, print them, and save them.
