This tab is part of the Bulk Input Stream Dialog and also of the Bulk Intermediate/Output Stream Dialog. These dialogs appear if you right-click on an input stream and select Simulation Data from the context menu or if you double-click on an input stream on the flowsheet.
It displays a set of collective environmental properties of the stream. Please note that all the properties in this dialog are always non-editable (even for input streams). They are calculated based on the composition of the stream and the environmental contribution factors of the component that are present in the stream (see Pure Component Properties Dialog: Aqueous Tab).
See also Environmental Properties of Bulk Streams for more information.
