The paper presents a way of basic parameters measurement – local losses coefficient ζ and line resistance coefficient λ – which determining pressure loses in ducts of ventilation systems. There was taken into consideration wide scope of cross-sectional areas from A = 0.051 m² to A = 2.323 m². All measurements were provided for constant Reynolds number Re = 100000.
