WebFor example, a mass flow rate of 1,000 kg/h of air at 1 atmosphere of absolute pressure is 455 SCFM when defined at 32 °F (0 °C) but 481 SCFM when defined at 60 °F (16 °C). In countries using the SI metric system of units, the term " normal cubic metre " (Nm 3 ) is very often used to denote gas volumes at some normalized or standard condition. WebThe next step is calculation of NM 3 /hr and SM 3 /hr. Gas volume is directly proportional to temperature and inversely proportional to pressure. Hence, gas flow at normal conditions is calculated as, NM 3 /hr = V× (T N /T)× (P/ P N) = 100× (298.16/353.16)× (2500/101.3) Gas flow = 2083.57 NM3/hr. Gas flow at standard conditions is ...
