modelSump
Extends from Icons.Color.Sump.
Information
Model of a column sump. The sump is basically a liquid storage with variable liquid level. This is not a separation stage. The vapour phase is not modelled explicitly, the vapour inlet and outlet properties are identical. The vapour phase is only needed to supply the pressure which is exerted on the liquid.
