Information
This model describes laminar flow. The conductance is controlled by the normalized signal sNorm, which varies between 0 and 1.
The flow is given by the equation:
where
where
 | : | Mass flow rate | |
 | : | Fluid density | |
| G | : | Conductance of the restriction | |
 | : | Pressure difference between ports a and b |
Limitations
This model is only valid for laminar flow. No checks are made if it is physically possible that the flow through the component actually is laminar.Reference
