( Aides duct and accessory ranges ) Pressure loss table for circular ducts PRESSURE LOSSES FROM CIRCULAR DUCTS T° = +15°C / Humidity rate = 50% / Atmospheric pressure = 101,325 Pa. For an airflow of 8000 m^/h in a 0 630 mm duct, the air speed is 7 m/s for a linear pressure loss of approx. 0.7 Pa/m. For an airflow of 6000 m^/h and a speed of 4 m/s, the required diameter is 710 mm for a pressure loss of approx. 0.25 Pa/m. Air Distribution Catalogue Edition no. 2

( Aides duct and accessory ranges ) Table of rectangular / circular equivalences RECTANGULAR / CIRCULAR EQUIVALENCES Example 1: to provide an airflow of Q = 1000 m3/h at a speed of 4 m/s, you can choose between: - A theoretical circular duct of 0 300 mm (i.e. 0 315 mm in practice). - A rectangular duct, where the different possible cross-sections are: 300 x 300 mm / 350 x 275 mm / 400 x 250 mm / 500 x 225 mm. Example 2: to provide an airflow of Q = 6000 m3/h at a speed of 4 m/s, you can choose between: - A rectangular duct with a cross-section of 800 x 700 mm. Given that for pressure...
