Table for Pressure Loss Calculation
By default, the table displays the calculation data for all components included in the selected section. When maximized, all components of the entire system are displayed.
| 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. |
| ζ | Zeta value of component. |
| Δp | Total of all pressure losses from pipe friction, zeta value or single resistance. |
| ΔpW | Static pressure recovery. |
| ΔpA | Total pressure loss of this component. |
Table for Sound Level Calculation
| Column | Description |
|---|---|
| No. | Component number. |
| Type | Component Type |
| 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. |
