Calculation of flow rates according to kitchen equipment dimensions (Norm DW 172)
The program allows you to calculate the flow rate generated by cooking elements in a kitchen according to their dimensions. For devices not listed, input the airflow generated by the device in “Extra Flow” in m3/h.
| Device | Quantity | Type | Width (mm) | Height (mm) | Flow (l/s) |

Total flow rate: 0 m3/h
Calculation of flow rates according to kitchen equipment power (Norm UNE-EN 16282-1)
- Factor de simultaneïtat: Enter a value based on the simultaneous use of kitchen appliances (large kitchens 0.6-0.8 or small kitchens 0.8-1)
- Position factor: Choose an option based on the hood's position in the kitchen.
- Kitchen air circulation: Choose an option based on the type of ventilation available in the kitchen.
- For devices not listed, input the airflow generated by the device in “Extra Flow” in m3/h.
Measurements of the hood and the height are from the cooking block to the hood.
