Hi,
In my project i need to make an heating oil loop which contain two heat exchangers: exhaust gas - heating oil and heating oil - working fluid. Because of that i need to add new substance to Hysys (heating oil - Duratherm S) but i don't know how to do it property. I have density, kinematic and dinamic viscosity, thermal conductivity and heat capacity in funcion of temperature and i don't know if it's possible to insert this data to Hysys database. How should i do that? Can somebody help me?
