Example 1. It is necessary to select a root air duct for a supply and exhaust unit for ventilation of a cottage with an estimated capacity of 380 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 a channel for the exhaust system in the private pool room, which extends from the root air duct to the center of the room. The estimated capacity in this branch is 160 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 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.
