Questions > Where can I find more information about the units operation? - Just click on the unit operation you want to know more about and press
F1. This will open the help for the specific unit operation
> I see there is an “ASME Steam” on the property package, what is the difference between this and the “NBS Steam” package?
- ASME steam is based on ASME 1967 steam tables and there are limitations on these tables in terms of pressure less than 15,000psia and temperatures greater than 32ºF and less than 1500ºF.
- NBS steam uses IAPWS steam tables from 1984 (IAPWS – international association property of water and steam), which are meant to have better calculations near Critical Point.
