tank model with varying liquid level
Extends from Icons.Color.ExpansionTank.
Information
This is a tank model for a liquid tank with a (inert) gas phase above the liquid level. This gas phase exerts a constant pressure on the liquid surface. The gas phase is not modelled explicitly and the pressure exerted by the gas phase is set by the user using the parameter p_gas. This pressure is then also propaged to the liquid inlet port.
