I <br />' Mass-Volume Calculations Of Extracted Gasoline Hydrocarbons - Continued <br /> . SIERRA LUMBER-375 West Hazelton Avenue, Stockton, CA <br />' 2. 18 October 2005 to 22 November 2005 <br />' The average analytical TPH-g concentration for this time interval was determined to be 140µg11(10-18-05 =<50µgll <br /> and 11-22-05 = 230µg11 , avg = 140 ug/L) The average flow rates during this time was calculated at 0 62 inches of <br /> water or approximately 50 cubic feet per minute(table 6),the operational period was equal to 840 hours of running time <br />' C =140 µg/1=0 000140 kg/m3 <br /> Q = 0 62 inches water = 50 ft3/min <br /> t= 840 hours(35 days) <br /> 1 Converting Q to m3/hour yields <br />' Q = (50 ft3/min) •(60 min/hour) •(0 0283168m3/ft3) =84 95 m3/hour <br /> M= C • Q •t= (0 000140 kg/m) •(84 95 m31hour) • (840 hours)= 9 99 kg of gasoline <br />' Converting kg of gasoline to pounds of gasoline yields <br /> 9 99 kg of gas •2 2046 lbs of gas/kg of gas=22 02 lbs of gasoline <br />' 22 02 lbs gas 135 days=0 63 lbs/day <br /> Converting pounds of gasoline to gallons of gasoline yields <br /> 22 02 lbs of gas •0 16 gal of gas/lbs of gas 3 52 gallons of gasoline <br /> I <br /> 1 <br /> I <br /> I <br />
