Example 1. It is necessary to select a root canal for a supply unit with a design capacity of 390 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 exhaust system of a private pool, which extends from the root air duct to the center above the surface of the water. The estimated capacity in this branch is 210 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 90x220 mm is suitable.
Example 3. A kitchen hood requires a flat duct. Estimated extraction capacity 110 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 50x110 mm is suitable.
