Does someone have a VI for Steam Tables?

[Steveo]

I'm looking to graph the saturation temperature for a given Pressure and Temperature input. Does someone have the Steam Tables in a VI?

Steve,

There seems to be trial downloads in excel formats.  you could then read from them and re-write them to a text file to be used later.  However, reading the download page policy should be done to see if that would be illegal.

Don't know if this will help, but you can find an open-source implementation of steam tables at http://pye.dyndns.org/freesteam/
It's a C library that you might be able to compile into a DLL for use in LabVIEW.

Some work has been done in freesteam (http://freesteam.sourceforge.net) to link it to LabVIEW. I haven't tested it; it was a user contribution.

You can see the code here:

Does Library file has something to do with 32bit and 64bit Labview?

freesteam being C code that gets compiled into a DLL, you bet that it is important to use a DLL compiled for the same bitness as what your LabVIEW environment is.

I have written a LabVIEW VI for the ASME Steam Tables.  It is currently in beta testing and if all checks out, we will start using it for designing/analyzing the steam plant for the Empire State VI (https://en.wikipedia.org/wiki/TS_Empire_State_VI)  at SUNY Maritime College.  The current version assumes pressure is known.  This LabVIEW VI is planned to be expanded later.  No name has been assigned yet.

Yes, I wrote one.  I am at SUNY Maritime and my students use it for Marine Engineering Design 1.

Hi maddog,

mind to share this VI, when you advertize it again after to more years?
