Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
There are two reservoirs at ambient pressure, the second one 25 m higher than the first one. The ideal pump is driven by a speed source, starting from zero and going up to 1.2 times nominal speed. To avoid water flowing back, the one way valve is used.
