What is a Nm3/h?

Believe this to be a volumetric flowrate (like cfm, cfh) - But not sure...

Also, Velocity in Nm/s? Looking for conversion to ft/s?

Re: What is a Nm3/h?

The N stands for Normal, meaning it was measured at standard temperature and pressure.

Nm³/h would be "cubic meter/hour". Though keep in mind it is for a specific temperature and pressure.

The "N" means "normal." regardless of actual temperature and pressure, the volume has been computed as though conditions were 101.325 kPa, 0 °C.

You may need to adjust for actual conditions, but at the same conditions, just divide by 60 because there are 60 minutes in an hour.

Re: What is a Nm3/h?

Can somebody tell me what is the meaning of m³(VN)/h in the compressor flow rate?

The "n" means normal, measured at 101.325 kPa, 0 °C. At other temperatures and pressures, the gas volume will vary. At identical conditions
1 m³/h x 1 h/60 min x (1 ft/0.3048 m)³ = 0.5886 ft³/min.

Next, if conditions are different (not mentioned in your question) apply temperature and pressure corrections using Ideal Gas Law (if reasonably applicable) or other gas equation of state.
