1 <br /> Mass-Volume Calculations Of Extracted Gasoline Hydrocarbons - Continued <br /> SIERRA LUMBER -375 West Hazelton Avenue, Stockton, CA <br /> 1 <br /> 4. 18 September 2003 to 09 October 2003 <br /> The average analytical TPH-g concentration for this time interval was determined to be 64 pg/l(09-18-03=78,ug/l and <br /> 10-09-03 =50 Ygll, avg =64 pg/l) The average flow rates during this time was calculated at 0 35 inches of water or <br /> Iapproximately 33 cubic feet per minute (table 6), the operational period was equal to 504 hours of running time <br /> C z 64 µg11=0 000064 kg/m' <br /> Q N 0 35 inches water r 33 ft'/min <br /> t= 504 hours(21 days) <br /> Converting Q to m'/hour yields <br /> Q=(33 ft'/mm)-(60 min/hour) -(0 0283168m'/ft')=56 07 m'/hour <br /> M=C - Q- t=(0 000064 kg/m')•(56 07 m'/hour)- (504 hours)= 1 81 kg of gasoline <br /> Converting kg of gasoline to pounds of gasoline yields <br /> 1 81 kg of gas - 2 2046 lbs of gas/kg of gas=3 99 lbs of gasoline <br /> I3 99 lbs gas/39 days=0 19 lbs/day <br /> Converting pounds of gasoline to gallons of gasoline yields <br /> 3 99 lbs of gas - 0 16 gal of gas/lbs of gas = =0 64 gallons of gasoline <br /> I <br /> I <br /> l� <br />
