Example 1. It is necessary to select a main channel for the exhaust system with a design capacity of 260 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 from the supply unit, which extends from the root air duct into the living room. The estimated capacity in this branch is 60 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 55x110 mm is suitable.
Example 3. A kitchen hood requires a flat duct. The estimated exhaust capacity is 210 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.
