The experimental studies‘ results of the aerodynamic drag of a swirling dust and gas flow passing through a network of air ducts of engineering and environmental systems are presented. The limits of the method applicability for determining the aerodynamic resistance coefficient of a gas-dust swirling flow passing in a round aspiration duct, without taking into account the solid phase presence in it, have been determined.
