The physical properties of H2O simulated in Aspen don’t match those listed in the book?
Thread Content
Why are the properties of water that I calculate using different versions of Aspen incorrect? For example: what are the density and viscosity of water at 28°C and 38°C? Everything doesn’t match what was checked – if the method for determining physical properties isn’t the right one, how else could this happen? Experts, please give some advice!
I’ve tried it too, and there’s indeed a difference!
That is because the material property method was not selected correctly; for water, steam-ta should be chosen. In each module such as the heat exchanger, there is a block options option that can be modified; simply change the properties of the cooling-side circulating water.
The selection of physical properties is very important; it is necessary to understand what properties should be chosen for each process.
Thank the devil, I tried it and it really works
