unity. Table 1 gives the numerical values for 29.92/P. To find acfm, multiply the scfm by the value found in the table opposite the vacuum pressure (P). A direct ratio for converting scfm to acfm (sL/s to aL/s) for various pressures is given in table 2. Multiply the scfm (sL/s...
However, if we use the density of whatever substance is going through the fan, we can easily convert volume to mass. This requires you to know one more piece of information about the medium in which the fan will operate. That's why SCFM exists. SCFM stands for standard CFM, and it's...
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. ...
