I have a question regarding enthalpy and entropy; the enthalpy value of water that I obtained using ASPEN simulation is negative
Thread Content
According to the tables I found in books, the enthalpy value of water is generally positive, whereas the values obtained from my ASPEN simulations are negative, with very large absolute values – over 200,000 KJ/Kmol. I would appreciate some guidance from experts: handshake
This is normal; enthalpy value has no meaning, but the enthalpy difference is useful!
What was said upstairs is correct; compare whether the enthalpy difference for Aspen is the same as that given in the book
In setup----specifications----global, try setting the atmospheric pressure and ambient temperature.
