Enter "((68 +460)/(T + 460))." Replace "T" with the actual temperature at the time of testing. This formula uses 68 as the standard temperature in Fahrenheit, but some people use other temperatures when calculating SCFM. Step 6 Press "=" to get the SCFM. Step 7 Double check your ...
Converting scfm to acfm: The following formula is used to convert scfm to acfm. acfm = scfm · ( Ps/ P )] · ( T + 459.67 ) / Ts or acfm = scfm ·Ear· ( T + 459.67 ) / Ts scfm = acfm / ( Ear· ( T + 459.67 ) / Ts) ) where: P = Actual pressure for the scf...
SCFM: 1,000 Ambient Temperature: 80°F Relative Humidity: 70% Inlet Pressure Drop: 0.3 psi (due to filter and silencer) Standard Conditions: CAGI Standards (14.5 psia, 0% RH and 68°F) We can use ourelevation tableto get our barometric pressure which can be interpolated as 14.18 psia. ...
