OK, where to even begin with this one...

First, the attached file is really a .pbit file but I can only upload .pbix files. So, download and rename from a .pbix file to a .pbit file.

Second, to make full use of this you will want the ASME Steam Tables Compact Edition as a PDF that you can download from here: ASME Steam Tables, Compact Edition | eBooks Gateway | ASME Digital Collection. I believe it is free or reduced cost if you are an ASME member. It is $15 otherwise. I cannot legally release the full .pbix file with the steam table data, hence the .pbit file.

So, this contains a boatload of stuff for thermodynamics as well as some fluid dynamics including:

• Couple dozen constants for atmosphere, gravity, speed of light, speed of sound, etc. all defined as individual measures
• Over 150 (I stopped counting) unit conversion measures for length, volume, mass, power, energy, thermal conductivity, etc.
• Twenty individual measures for temperature conversions between Celsius, Farenheit, Kelvin, Rankin and Reaumur
• A bunch of thermodynamics equations as measures, many for ideal gases
• Rayleigh flow, Fanno flow and Isentropic flow tables. I have a page in the report for each of these with a mobile view configured.
• In addition to the water and steam tables in US Customary and SI units, also includes interpolation tables
• Additional tables for chemical properties, thermodynamic properties and specific heat ratios for gases

Could be useful even without the water and steam tables. I plan on working on this one some more over time to add additional calculations and things. I'll post a comment when I update it with notes about what was added/changed. 

If you find any errors or if you have suggestions for this, please comment!!

Oh, and just so we are clear, I make no guarantees that any of this information is accurate, so use at your own risk!

wow, there is a lot in this. Thanks!

As a mechanical Engineer focused on building operations, I've been exploring PowerBI as an approachable tool for other small/medium size energy consultants and commissioning agents to review BMS and HVAC equipment Trend Data. This pbit has a bunch of helpful measures for psychrometric calculations (dewpoint or enthalpy from temp and RH%, etc. )

Thank you for sharing!
