WOLFRAM SYSTEM MODELER
OpenTankModel of a tank under ambient pressure |
SystemModel["Modelica.Thermal.FluidHeatFlow.Components.OpenTank"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a simple model of an open tank with volume A*h. The level and the temperature of the medium are measured and provided as output.
Note: If the level of the medium reaches 0 (minimum) or h (maximum), an assertion is triggered.
Note: The flowPort is assumed to be at the bottom. Therefore the pressure at the flowPort is ambient pressure + level*rho*g.
It is assumed that the medium in the tank has the same temperature over the whole volume, i.e. mixed thoroughly.
Via the optional heatPort the medium in the tank can be cooled or heated.
