Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Base class for one dimensional flow models. It specializes a PartialTwoPort with a parameter interface and icon graphics.
Parameters (10)

| length |
Value: Type: Length (m) Description: Length |
| isCircular |
Value: true Type: Boolean Description: = true, if cross sectional area is circular |
| diameter |
Value: Type: Diameter (m) Description: Diameter of circular pipe |
| crossArea |
Value: Modelica.Constants.pi * diameter * diameter / 4 Type: Area (m²) Description: Inner cross section area |
| perimeter |
Value: Modelica.Constants.pi * diameter Type: Length (m) Description: Inner perimeter |
| roughness |
Value: 2.5e-5 Type: Roughness (m) Description: Average height of surface asperities (default: smooth steel pipe) |
| V |
