Example 1. It is necessary to select an air duct for supply and exhaust ventilation, which will go from the installation to the apartment. The estimated productivity is 300 m?/h. The speed in the root section should be within 5-6 m/sec. According to the table, an air duct with a cross section of 90x220 mm fits these parameters.
Example 2. It is necessary to select an air duct that extends from the root air duct into the bedroom. The estimated capacity in this branch is 120 m³/h. The speed in the side air duct should be within 3-4 m/sec. According to the table, an air duct with a cross section of 60x204 mm is suitable.
Example 3. For exhaust from the laundry room you need a root flat duct. The estimated exhaust capacity is 270 m³/h. The speed is allowed within 5-6 m/sec. For this task, according to the table, an air duct with a cross section of 60x204 mm is suitable.
