Is the N in Nm3/min under standard conditions?
Thread Content
In Nm3/min, the N refers to standard conditions – are these standard conditions defined as 0 degrees and 101.325 KPa (one atmosphere), or is it 20 degrees and one atmosphere in an engineering context?
Nm3/min represents standard cubic meters per hour; it refers to the conversion of the gas volume flow rate into a flow rate under conditions of 0°C and 101.325 kPa. For example, a gas flow rate of 300 m3/min at 0°C and 0.3 MPA is equivalent to 900 Nm3/min. In production, for process calculations and management purposes, all gas flow rates must be converted into Nm3/min
Nm3/min is standard cubic meters per minute
Indeed, Nm3/min refers to standard cubic meters per minute
