COMPUTATION SHEET <br /> PROJECT TITLE: USA Gasoline Station No. 65 PROJEC-2007-0065-01 <br /> I DESCRIPTION:^ Mass Emission rates SHEE' 2 OF 4 <br /> PREP. BY:K. Nagaraju DATE: 91512003 CHK BY: G. Kowtha DATE: <br /> DATA <br /> The following parameters listed below were recorded during the source testing: <br /> 811!2003 <br /> Total influent air flow rate(scfm) 78.56 <br /> Influent temperature(°F) 80 <br /> Estimated Effluent temperature(oF) 85 <br /> Applied vacuum("WC) 18 <br /> ^ Influent concentration of TPHG(mg/m3) 36,000 <br /> a Influent concentration of benzene(mg/m3) <10 <br /> influent concentration of MTBE(mg/m3) 57 <br /> Effluent concentration of TPHG(mg/m3) <12 <br /> Effluent concentration of benzene(mg/m3) <0.12 <br /> Effluent concentration of MTBE(mg/m3) <0.12 <br /> CALCULATION <br /> The total influent flow rate will be corrected to scfm for pressure using the formula listed below <br /> Pressure corrected influent flow rate = Total influent air flow rate scfm'{(406.8"WC-"WC)l406.8"WC} <br /> l Pressure corrected influent flow rate = 78.56*{(406.8"-18)14116.8"WC) <br /> Pressure corrected influent flow rate = 75.08 <br /> Temperature Corrected influent flow rate Pressure corrected flow rate *{[460 R +68 deg F]/[deg F+460 R]} <br /> Total Influent Flow Rate after pressure and: <br /> temperature corrections - 73.61 aofm <br /> Source Test Calcs&Summary - <br /> j . <br />
