How to convert m3/h to Nm3/h? I don’t understand! ! ! !

It is necessary to know that for m3/h (with the symbol set as V), the corresponding temperature T (273 + degrees Celsius) and pressure P (this is absolute pressure, not gauge pressure as commonly understood) apply. For Nm3/h (V0), the corresponding temperature T0 is 0, or 273 K (absolute zero, measured in Kelvin; more precisely, 273.15), and the pressure P0 is 1 atmosphere (101.325 kPa). Calculated using the formula P0*V0/T0=P*V/T; V0=P*V*T0/T, with P0=1, which is not shown in the formula. 2. In production workshops, it’s really not necessary to be so complicated when it comes to pressure conversion. Today’s pressure gauges use units such as MPa and kPa, and 1 atmosphere equals 101.325 kPa, which represents a difference of 1%. In production environments, people usually ignore such unit conversions and simply assume that 0.1 MPa is equivalent to 1 atmosphere.
Are the operating conditions for the former specified? Otherwise, it’s impossible to convert
You need to know the pressure, and then you can convert it using PV=nrt
Gas state equation PV=NRT
