1 <br />' Mass-Volume Calculations Of Extracted Gasoline Hydrocarbons - Continued <br /> SIERRA LUMBER -375 West Hazelton Avenue, Stockton, CA <br /> I <br /> 2• 24 July 2003 to 13 August 2003 <br />' The average analytical TPH-g concentration for this time interval was determined to be 13 5,ug/l(07-24-03 =27 pg/L <br /> and 08-13-03=less than 50,ug1l,avg = 13 5 pg/1) The average flow rates during this time was calculated at 0 40 inches <br />' of water or approximately 34 cubic feet per minute(table 6),the operational period was equal to 480 hours of running <br /> time <br /> C z 13 5 µg/1=0 0000135 kg/m' <br /> I Q = 0 40 inches water= 34 ft3/min <br /> t=480 hours(20 days) <br />' Converting Q to m'/hour yields <br /> Q=(34 ft'/mm)•(60 min/hour) •(0 0283168m'/ft')=57 77 m'/hour <br /> M=C • Q • t=(0 0000135 kg/m')•(57 77 m'/hour) • (480 hours)=0 37 kg of gasoline <br /> I <br /> Converting kg of gasoline to pounds of gasoline yields <br />' 0 37 kg of gas • 2 2046 lbs of gas/kg of gas=0 83 lbs of gasoline <br /> 0 83 lbs gas 120 days=0 04 lbs/day <br /> Converting pounds of gasoline to gallons of gasoline yields <br /> 0 83 lbs of gas • 0 16 gal of gas/lbs of gas =0 13 gallons of gasoline <br /> • <br /> i <br />
