Vapor Extraction System Sample Calculations <br /> Moore Petroleum,Inc, 14800 W Frontage Road,Manteca,CA <br /> The standardized conversion is accomplished through the use of the ideal gas law relationship <br /> PI-Vi P2-V2 <br /> T, T2 <br /> where, <br /> p, = influent pressure, 13 9 psxa <br /> V, = influent flow rate, 45 CFM <br /> T, — influent temperature, 548 R <br /> P2 = standard atmospheric pressure, 14 7 Asia <br /> V2 = influent standardized flow rate, m SUM <br /> T2 = standard room temperature, 537 R <br /> The preceding equation may be solved for V2, which will be the corresponding influent flow rate <br /> in SUM <br /> V _ p, V, T2 _ 13 9psia-45CFM 537R _ 41 SCFM <br /> 2 Ti P2 548R 14 7psia <br /> Therefore, the influent flow rate is at 41 SCFM <br />
