This verification is based on the knowledge of circular and rectangular cross-section ducts’ properties and the new cross-section contains both aforementioned. These studies are aimed at finding ways of reducing the necessary measurements to determine the average flow rate in ventilation air ducts. Due to the size of the ducts it was decided to determine the flow rate based on the integration of flow velocity over the considered crosssection. This method requires knowledge of velocity distribution in the cross section. The approximation of measured actual profile by the basic and modified Prandtl power-law velocity profile was verified.
