Appendix D - SVE Volume-Mass Calculations <br /> AGE-NC Project No. 95-0130 <br /> Page 3 of 3 <br /> 3) 23 May 2013 - 17 June 2013 <br /> The average analytical TPH-g concentration for this time interval was determined to be 125 pg/I <br /> (05/13 =140 pg/l, 06/13= 110 pg/l; avg. = 125 pg/1). During this time interval, the average flow rate <br /> was calculated at 1.0 inches of water (2-inch pipe) or approximately 55 cubic feet per minute <br /> (nomograph); the operational period was equal to 599 hours of running time (Table 2). <br /> TPH-g (total petroleum hydrocarbons quantified as gasoline) <br /> C = 125 pg/I = 0.000125 kg/m' <br /> Q = 1.00 inches water = 55 ft'/min <br /> t = 599 hours (25 days) <br /> Converting Q to m'/hour yields: <br /> Q = (55 ft'/min) • (60 min/hour) • (0.0283168 m'/ft') = 93.5 m'/hour <br /> M = C • Q • t = (0.000125 kg/m') • (93.5 m'/hour) • (599 hours) = 7 kg of TPH-g <br /> Converting kg of TPH-g to pounds of TPH-g yields: <br /> 7 kg of TPH-g • 2.2046 lbs. of TPH-g/kg of TPH-g = 15.4 lbs of TPH-g <br /> Converting pounds of gasoline to gallons of gasoline yields: <br /> 15.4 lbs. of gas • 0.16 gal of gas/lbs. of gas = 2.5 gallons of gasoline <br /> Advanced GeoEnvironmental,Inc. <br />
