Appendix D - SVE Volume-Mass Calculations <br /> AGE-NC Project No. 95-0130 <br /> Page 3 of 3 <br /> 3) 09 November 2012 - 18 December 2012 <br /> The average analytical TPH-g concentration for this time interval was determined to be 330 pg/l <br /> (11/12 =360 pg/I, 12/12= 300 pg/1; avg. = 330 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 866 hours of running time (Table 2). <br /> TPH-g (total petroleum hydrocarbons quantified as gasoline) <br /> C = 330 pg/l = 0.000590 kg/m3 <br /> Q = 1.00 inches water = 55 ft'/min <br /> t = 866 hours (28 days) <br /> Converting Q to m3/hour yields: <br /> Q = (55 ft'/min) • (60 min/hour) • (0.0283168 m3/ft3) = 93.5 m3/hour <br /> M = C • Q • t = (0.000360 kg/m3) • (93.5 m3/hour) • (866 hours) = 29.2 kg of TPH-g <br /> Converting kg of TPH-g to pounds of TPH-g yields: <br /> 29.2 kg of TPH-g • 2.2046 lbs. of TPH-g/kg of TPH-g = 64.2 lbs of TPH-g <br /> Converting pounds of gasoline to gallons of gasoline yields: <br /> 64.2 lbs. of gas • 0.16 gal of gas/lbs. of gas = 10.3 gallons of gasoline <br /> Advanced CeoEnvironmental,Inc. <br />
