Example 1. It is necessary to select a root air duct for the apartment's supply system with a design capacity of 250 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 60x204 mm fits these parameters.
Example 2. It is necessary to select an air duct that extends from the root duct and will enter the room. The estimated capacity in this branch is 90 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 60x120 mm is suitable.
Example 3. A flat duct is required for a kitchen hood. Estimated extraction capacity 400 m?/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 90x220 mm is suitable.
