Example 1. It is necessary to select a root air duct for the exhaust ventilation of the sauna with a design capacity of 340 m³/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 for the supply ventilation system of a private house, which extends from the root air duct into the living room. 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. A kitchen hood requires a 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.
