r ! <br /> Tank Anchoring: All tanks must be anchored whenever they are installed in a saturated <br /> conditions. Using soil as the anchor has become an acceptable alternative to concrete. <br /> • Flotation potential is the displacement of the tank calculated by its volume in cubic feet. <br /> Line A Calculate cubic feet of tank. <br /> inches high, x inches wide, x /7 3 inches Long, _ cubic inches. <br /> Divide this number by 1728 to equal'cubic feet. <br /> Line B Next convert the displacement to the weight of water. <br /> 07 ` (from line A) cubic feet x 62.4 (weight of 1 cubic foot of water) x 1.5 (fudge factor) _ <br /> a 1t o lbs of lift potential. <br /> Line C Calculate weight needed to counter buoyancy. <br /> lbs. (Displacement weight from line B.) Z10`° lbs. (weight of tank from <br /> manufacture) = lbs. Of soil needed to anchor tank.1/ o 5 0 # <br /> Line D Weight over the tank cover needed, plus safety factor. <br /> 741 inches wide of tank cover x /inches long of tank cover, divided by 144 <br /> _Square feet of cover x 0.083 ( 1 inch in foot decimal)_ cubic foot space of <br /> 1 inch of tank cover. <br /> Line E Calculated weight of 1 inch of space over entire cover. <br /> cubic feet of space ( from line D) x 100 lbs./cubic foot of= lbs./inch space above <br /> cover. <br /> Line F Calculate inches of soil needed to counter buoyancy . <br /> lbs. (from line C) divided by,?"/& lbs. per inch of soil (from line E)=inches need over <br /> tank cover. <br /> /. /� - 2z7� 9/ <br />
