Table for flow paths
This table shows the calculation data for all flow paths of the selected system. It provides an overview over all ending components of the network. If you select a flow path, the table Pipe sections displays all corresponding pipe sections. The most unfavorable flow path is highlighted in a different color. You can also select the most unfavorable flow path by pressing U.
| Column | Description |
|---|---|
| (without title) | Pipe type: S: Sewage water R: Rain water |
| No. | Flow path number. |
| Name | Name of the drainage element. |
| DU | Connection value |
| Qc | Water inflow. |
| A | Connected roof area. |
| Qr | Rainwater outflow rate. |
| C | Discharge coefficient. |
| DN | Dimensioning target. |
Table for pipe sections
This table shows the calculation data for all pipe sections of the selected flow path. If you select a pipe section, the table Ventilated via pipe section(s) displays all corresponding ventilation pipe sections.
Apply pipe section data globally
Opens the dialog Define pipe sections. This function allows you to assign or reset certain properties of selected or all pipe sections.
Unfix / fix pipe sections
This function allows you to fix or unfix the dimensions of all pipe sections. If values are displayed in bold in the DN column, the dimension of the respective pipe sections will not be adjusted during the calculation. This is sensible when calculating existing systems. If the dimensions of some pipe sections have been fixed already, you will be asked whether to fix or unfix all pipe sections.
| Column | Description |
|---|---|
| (without title) | Pipe type: S: Sewage water R: Rain water M: Mixed water |
| No. | Number of the duct section. |
| Type | DP: Down pipe G: Ground pipe ColP: Collector pipe S: Collecting pipe SCP: Single connector pipe (i): inside the building (o): outside the building Pipe type can be changed in the table. |
| L | The length of the pipe section determined in accordance with the norm, taking into account all relevant fittings. The length be changed in the table. The new length will be distributed among all ducts of the duct sections proportionately to constructed length. All pipes affected by the change in length will be displayed bold in the tables for duct sections and components. |
| H | Height of pipe section. |
| U | Number of individuals ( if calculated according to SP 30.13330.2016 and SP 30.13330.2020) |
| N | Number of sanitary ( if calculated according to SP 30.13330.2016 and SP 30.13330.2020) |
| P | Probability of use ( if calculated according to SP 30.13330.2016 and SP 30.13330.2020). |
| NP | Product of the number of sanitary objects and the probability of use ( if calculated according to SP 30.13330.2016 and SP 30.13330.2020). |
| α | Simultaneity factor ( if calculated according to SP 30.13330.2016 and SP 30.13330.2020) |
| DN | Nominal diameter of pipes in this pipe section. The nominal diameter can be changed in the table. The value is then fixed and will not be adjusted by the software during calculation. Fixed values are shown in bold. |
| DU | Connection value. |
| Qww | Waste water discharge. |
| Qp | Pump flow rate, if a pump exists. |
| Qc | Continuous flow rate. |
| Qtot | Total waste water discharge. |
| A | Connected roof area. |
| Qr | Rainwater outflow rate. |
| Qm | Mixed water outflow. |

| h/d | Filling degree. The tooltip in this field shows the actual- and max-condition of the current loads. |
| w | Flow velocity in collecting- and ground pipes. |
Table Ventilated by pipe section(s)
This table shows the calculation data for all ventilation duct sections of the selected pipe section.
Lock/unlock pipe sections
This function allows you to fix or unfix the dimensions of all pipe sections. The column NPS displays all values in bold and pipe section dimensions are not adjusted during calculation. This is sensible when calculating existing systems. A repeated click on this button unfixes all dimensions. If the dimensions of some pipe sections have been fixed already, you will be asked whether to fix or unfix all pipe sections.
| Column | Description |
|---|---|
| (without title) | Pipe type: L: Ventilating pipe |
| No. | Number of the ventilating pipe. |
| Type | Type of ventilation pipe. The ventilation pipe can be changed in the table. |
| L | The length of the pipe section determined in accordance with the norm, taking into account all relevant fittings. The length be changed in the table. The new length will be distributed among all ducts of the duct sections proportionately to constructed length. All pipes affected by the change in length will be displayed bold in the tables for duct sections and components. |
| H | Height of pipe section. |
| DN | Nominal diameter of pipes in this pipe section. The nominal diameter can be changed in the table. The value is then fixed and will not be adjusted by the software during calculation. Fixed values are shown in bold. |
Adjusting nominal diameters
If calculated nominal diameters deviate from those constructed, calculated nominal diameters can be transferred into the model. You can adjust the nominal diameters for the entire network or for partial networks.
