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. 000021228 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000021228 653__ $$aVentilation, Rounded rectangular cross-sectional area, Minor (local) losses coefficient, Line resistance coefficient. 000021228 7112_ $$aEngineering Mechanics 2017$$cSvratka, CZ$$d2017-05-15 / 2017-05-18$$gEM2017 000021228 720__ $$aPeszynski, K.$$iKasprowicz, T.$$iSmyk, E.$$iOlszewski, L. 000021228 8560_ $$ffischerc@itam.cas.cz 000021228 8564_ $$s987231$$uhttps://invenio.itam.cas.cz/record/21228/files/0050.pdf$$yOriginal version of the author's contribution in proceedings, page 50, section KEY. 000021228 962__ $$r21225 000021228 980__ $$aPAPER
