Dear all
in HYSYS properties we will find properties like STANDARD IDEAL LIQUID VOLUME , liquid volume at standard conditions , how do we know the exact temperature and pressure at which standard conditions were defined, Actually there are so many standard conditions available right now like GPSA follow their own and API follow their own ( some people use P= 100 KPa & some people use P= 101.325 KPa etc.), how do we know In HYSYS what are the exact conditions
they follow
thank you
regards,
Satish

Satish:
As a customer of HySys, you have the right and means to raise the phone and call them asking them the very specific and very important question you raise.
You can also contact them through the Internet or email. All this is explained in your simulation program's documentation. If you and your company are paying the tens of thousands of dollars yearly to operate and depend on HySys you have customer rights.
However, if you have not paid for your HySys simulation program, you have problems.

You will see quite a few postings in these forums from me expressing dismay at the lack of willingness on the part of many intelligent people to define (just once) what THEY mean by "standard" conditions. This is NOT simple or obvious. There are "standard" conditions as apply to gases and as apply to liquids. In metric, Imperial, and SI units. In chemistry/sciences and in engineering. You will also find a lot of differences from one industry to another. So, when you talk about "standard" conditions, I don't know what you mean unless you've first defined standard conditions. Though not restricted to engineering, much of what we do requires precision and accuracy. All the precision and accuracy in the world is of little value if you can't communicate the end result to the end user, and you can't do this if HE/SHE doesn't know what you mean.

Thank you Art and Zauberberg for correct answer and direction.

Check out definition here...
You may find the HYSYS standard condition definition in HYSYS Simulation Basis file (Check out HYSYS Doc)

Thank you all for your valuable guidance ,
JOE WONG I got it in SIMULATION BASIS document provided by ASPEN , you have shown me the exact path which saved my time
ART had shared his experience with standards in this forum & eng tips forum which is really giving great knowledge of standards for newbie’s like me
Link provided by Zauberberg also of great help.
thank you for all JEDI's for always helping the people to grow
