packageNoFriction
No pipe wall friction, no static head
Extends from Modelica.Icons.Package (Icon for standard packages), PartialWallFriction (Partial wall friction characteristic (base package of all wall friction characteristics)).
Information
This component sets the pressure loss due to wall friction to zero, i.e., it allows to switch off pipe wall friction.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_mu (from PartialWallFriction) | true | = true, if mu_a/mu_b are used in function, otherwise value is not used |
| Boolean | use_roughness (from PartialWallFriction) | true | = true, if roughness is used in function, otherwise value is not used |
| Boolean | use_dp_small (from PartialWallFriction) | true | = true, if dp_small is used in function, otherwise value is not used |
| Boolean | use_m_flow_small (from PartialWallFriction) | true | = true, if m_flow_small is used in function, otherwise value is not used |
| Boolean | dp_is_zero (from PartialWallFriction) | false | = true, if no wall friction is present, i.e., dp = 0 (function massFlowRate_dp() cannot be used) |
| Boolean | use_Re_turbulent (from PartialWallFriction) | true | = true, if Re_turbulent input is used in function, otherwise value is not used |
