In most systems, the actual flow rate in cubic feet per minute at flowing conditions is known. To use this value will require the conversion to standard flow rate at standard conditions (60°F and 14.7 psi) for use in the various formulas. The suggested method of conversion is given below:
ACFM (Actual cubic ft./min.):
Pressure (psig):
Temperature (F):
SCFM:
