For piping family categories, the Part Type determines how pressure loss is calculated.
| Family Category | Part Type | Behavior |
|---|---|---|
| Mechanical Equipment | Breaks Into | |
| EndCap | ||
| Inline Sensor | ||
| Normal | ||
| Valve - Breaks into | ||
| Pipe Accessories | Attaches To | The pipe accessory attaches to the face of a pipe in Revit. No pressure drops are calculated since the pipe accessory is not breaking into the pipe. |
| Breaks Into | The pipe accessory breaks the pipe into two pipe segments. Pressure drops are calculated for the individual pipe segments. | |
| End Cap | The pipe accessory attaches (snaps) to the end of a pipe. No flow or pressure drop is calculated on the segment where the endcap is attached. | |
| Inline Sensor | Not used. | |
| Normal | The pipe accessory breaks the pipe into two separate pipe segments. Pressure drops are calculated for the individual pipe segments. | |
| Sensor | Not used. | |
| Valve - Breaks Into | The pipe accessory breaks the pipe into two separate pipe segments. Pressure drops are calculated for the individual pipe segments using predefined K-factor tables. | |
| Valve - Normal | The pipe accessory attaches (snaps) to the end of a pipe. If a pipe is connected to a secondary pipe accessory connector, that pipe will be seen as another pipe segment. In that case, pressure drops are calculated for the individual pipe segments using predefined K-factor tables. | |
