Table for pressure loss calculation
The table shows the calculation data of all components contained in the selected pipe section.
| Column | Description |
|---|---|
| No. | Component number. |
| Type | Component type: L: Pipe |
| Name | Name of the component. |
| l | Length of the duct or installation lengths of the component, respectively. |
| a, b, c, d d1, d2, d3, d4 | Inlet, outlet and branch dimensions of fittings and air ducts. For rectangular or oval components the dimensions are output with the letters a-d, for round components with d1-d4. |
| R | R-value for straight pipes or ducts. |
| l*R | Pressure loss due to pipe friction. |
| Zeta | Zeta value of component. |
| dp | Total of all pressure losses from pipe friction, zeta value or single resistance. |
| dpFP | Static pressure recovery. |
| dpA | Total pressure loss of this component. |
Table for sound level calculation
| Column | Description |
|---|---|
| No. | Component number. |

| Name | Name of the component. |
| l | Length of the duct or installation lengths of the component, respectively. |
| a, b, c, d d1, d2, d3, d4 | Inlet, outlet and branch dimensions of components. For rectangular or oval components the dimensions are output with the letters a-d, for round components with d1-d4. |
| Octave frequency bands | Unweighted sound power level of all eight octave bands for this component. |
| Residual dB | Unweighted sound power level at the end of the component. |
