1 I <br /> Mass-Volume Calculations Of Extracted Gasoline Hydrocarbons - Continued <br /> SIERRA LUMBER -375 West Hazelton Avenue, Stockton, CA <br />' 3. 13 August 2003 to 18 September 2003 <br /> The average analytical TPH-g concentration forthis time interval was determined to be 39,ug/1(08-13-03=less than 50 <br /> ,ugll and 09-18-03 =78 yg/l,avg =39 yg/1) The average flow rates during this time was calculated at 0 425 inches of <br />' water or approximately 34 5 cubic feet per minute(table 6),the operational period was equal to 864 hours of running <br /> time <br />' C = 39 µg/1=0 000039 kg/m' <br /> Q = 0 425 inches water = 34 5 ft'/min <br /> t= 864 hours(36 days) <br /> IConverting Q to m'/hour yields <br /> Q=(34 5 ft'/min) -(60 min/hour) -(0 0283168m3/ft')=58 62 m'/hour <br />' M=C - Q - t=(0 000039 kg/m') -(58 62 m'/hour)- (864 hours)= 1 98 kg of gasoline <br /> Converting kg of gasoline to pounds of gasoline yields <br />' 1 98 kg of gas -2 2046 lbs of gas/kg of gas =4 35 lbs of gasoline <br /> 4 35 lbs gas/39 days=0 12 lbs/day <br /> Converting pounds of gasoline to gallons of gasoline yields <br /> 4 35 lbs of gas - 0 16 gal of gas/lbs of gas =0 70 gallons of gasoline <br /> r <br /> i <br /> i <br />
