(2) Ventilatsiooniseadme rõhulang Δp m sisaldab ventilatsiooniseadmekomponentide summaarset rõhulangu ning rõhulangu ventilaatori ja ventilatsiooniseadme ühenduspunktis. Filtrite rõhulanguna kasutatakse keskmist kasutusaegset rõhulangu, mis arvutatakse, liites algrõhulangule kolmandiku lõpp- ja algrõhulangude vahest.

(3) Torustiku rõhulang Δp t on torustiku ja lõppelementide summaarne rõhulang, mis sisaldab nii enne kui pärast ventilatsiooniseadet paikneva torustiku rõhulange.

(4) Kui rõhulangude ehitusprojekti andmed puuduvad, siis arvutatakse rõhulangud, kasutades tabelis 12 toodud andmeid.

Tabel 12. Ventilatsiooniseadme ja torustiku osade rõhulangud süsteemidele, mille õhuhulk on ≥ 0,25 m³/s. Madalale, normaalsele ja kõrgele rõhulangule vastavad ligikaudsed ventilatsiooniseadme komponentide otsapinna kiirused, mis on vastavalt 1,5; 2 ja 2,5 m/s.

(5) Muutuva õhuvooluhulgaga süsteemi lihtsustatud arvutuses eeldatakse, et torustiku rõhulang püsib muutumatuna.
