Questions from WeChat groups: When people talk about an air compressor with a capacity of 25 m3/min, do they mean cubic meters or cubic feet? And why is it necessary to multiply by 60 to get the air volume?
Volume at standard atmospheric pressure. 60 is the conversion factor between hourly air volume and minute air volume.
For the metric system, *60 refers to the air volume per hour
If it’s the standard value, it should be like this—25 Nm3/min. There’s an extra N. Otherwise, it is a volume representation with no other requirements. For reference.
