Mass-Volume Calculations Of Extracted Gasoline Hydrocarbons - Continued SIERRA LUMBER- 375 West Hazelton Avenue, Stockton, CA ' 4. 14 May to 06 June 2001 The average analytical TPH-g concentration for this tune interval was determined to be 1,900 ,ug/l (05-14-01= ' 2,000pg/L and 06-06-01 = 1,800,ug/L, avg = 1,900,ug/L) The average flow rates during this time was calculated at 0 54 inches of water or approximately 40 cubic feet per minute(table 5),the operational period was equal to 552 hours of running time ' C = 1,900 Mg/l=0 001900 kg/m' Q = 0 54 inches water = 40 ft'/mire ' t=552 hours Converting Q to m'/hour yields ' Q=(40 ft'/inun) -(60 rrnn/hour)-(0 0283168in'/ft')=67 96 m3/hour M=C- Q - t=(0 001900 kg/m) -(67 96 m'/hour) - (552 hours)=7128 kg of gasoline ' Converting kg of gasoline to pounds of gasoline yields 71 28 kg of gas - 2 2046 lbs of gas/kg of gas= 157 14 lbs of gasoline Converting pounds of gasoline to gallons of gasoline yields 157 14 lbs of gas - 0 16 gal of gas/lbs of gas = 25 14 gallons of gasoline 5. 14 May to 06 June 2001 The average analytical TPH-g concentration for this time interval was determined to be 1,900 ug/l (06-06-01= 1,800,ug/L and 06-25-01 = 1,200 yg/L, avg = 1,500,ug/L) The average flow rates during this time was calculated at 0 42 inches of water or approxunately 37 cubic feet per minute(table 5),the operational period was equal to 456 hours of running time ' C 1,500 gg/l=0 001500 kg/m' Q ; 0 42 inches water= 37 ft3/nun ' t=456 hours Converting Q to m'/hour yields ' Q =(37 ft}/min) -(60 nun/hour) -(0 0283168m3/ft')=62 86 r0hour M=C- Q -t=(0 001500 kg/m') -(62 86 m'/hour) - (456 hours)=42 99 kg of gasoline ' Converting kg of gasoline to pounds of gasoline yields 42 99 kg of gas- 2 2046 lbs of gas/kg of gas=94 79 lbs of gasoline Converting pounds of gasoline to gallons of gasoline yields 99 79 lbs of gas - 0 16 gal of gas/lbs of gas = 15 16 gallons of gasoline
