Introduction
These properties are related to the energy contained in the stream, e.g. specific heat, enthalpy, etc. These will only be shown if the user has chosen to display the Energy (Thermodynamic) Properties on the Plant Model - Views tab page or from the Include Properties dropdown list on the first page of the material flow section.
