' Appendix G - SVE Volume-Mass Calculations <br /> AGE-NC Project No 95-0130 <br />' Page 3 of 3 <br />' 3) 07 February 2006 - 14 March 2006 <br /> The average analytical TPH-g concentration for this time interval was determined to be 1,650 gg/l <br />' (02-07-06= 1,300 µg/1 and 03-14-06 = 2,000 gg/l, avg = 1,650 µg/l) The average flow rate was <br /> calculated at 3 20 Inches of water or approximately 94 cubic feet per minute (nomograph), the <br /> operational period was equal to 840 hours of running time (Table 6) <br />' TPH-g (total petroleum hydrocarbons quantified as gasoline) <br /> IC = 1,650 µg/1=0 001650 kg/m3 <br /> Q = 3 20 Inches water = 94 ft3/mm <br />' t= 840 hours (35 days) <br /> Converting Q to m3/hour yields <br /> rQ= (94 ft/mm) • (60 mm/hour) • (0 0283168m3/ft3) = 159 7 m3/hour <br /> lie M= C • Q • t= (0 001650 kg/m3) • (159 7 m3/hour) • (840 hours)=221.3 kg of TPH-g <br /> Converting kg of TPH-g to pounds of TPH-g yields <br /> I22134 kg of TPH-g • 2 2046 lbs of TPH-g/kg of TPH-g=488 lbs of TPH-g <br /> IConverting pounds of gasoline to gallons of gasoline yields <br /> 488 lbs of gas • 0 16 gal of gas/lbs of gas = 78 gallons of gasoline <br /> I <br /> Advanced GeoEnvironmental,Inc <br /> I <br />
