( 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
