What is the difference between cfm and acfm

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Students Click Here. Related Projects. A common question. Not sure what ICFM is though? I Can't Find Mum to help me. Inlet cfm I reckon. Cfm, ICFM, scfm, at sea level basically all the same.

ACFM depends on the pressure it's quoted at. So might be the same or if quoted at say psi is the actual output at that pressure. Because this will be much lower than the others my cynical hat says vendors will quote the bigger numbers. This converts to a density of 0.

The CFM values are calculated at a pressure under 90psi whereas the SCFM values are calculated after expanding the gas to a standard value of The standardized conditions can vary from place to place and so values of the rate of flow of the same mass may be different in other places.

Skip to content There are a lot of factors one has to look out for when using the measurement units. What is CFM? What is SCFM? To calculate SCFM values, the air or gas is expanded to a standard condition which is around CFM is more relevant to the internal capacity of an air compressor. SCFM is more indicative of how the gas which is pressurized to a standard value will perform at the end point applications.
