/333 cP 1666 s/,-a w <br /> anti 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 displacemp v its volume in cubic feet. <br /> Line A Calculate cubic feet of tan <br /> 3 9 inches high, x 71V inches wit UW cubic inches. <br /> Divide this number by 1728 to equal_ <br /> Line B Next convert the displacement to the weight of water. <br /> All (from line A)cubic feet x 62.4 (weight of 1 cubic foot of water) x 1.5 (fudge factor) _ <br /> A7oso lbs of lift potential. <br /> Line C Calculate weight needed to counter buovancv. <br /> y70so lbs. (Displacement weight from line B.) - / ovo lbs. (weight of tank from <br /> manufacture) = lbs. Of soil needed to anchor tank. iioz0 # <br /> Line D Weight over the tank cover needed, plus safety factor. <br /> 7W inches wide of tank cover x /73 inches long of tank cover. divided by 144 <br /> =J 9 Square feet of cover x 0.083 ( 1 inch in foot decimal) = 7• H cubic foot space of <br /> 1 inch of tank cover. <br /> Line E Calculated weight of 1 inch of space over entire cover. <br /> 7. y cubic feet of space ( from line D) x 100 lbs./cubic foot of= 790 lbs./inch space above <br /> cover. <br /> Line F Calculate inches of soil needed to counter buoyancy . <br /> /Yoso lbs. (from line C) divided by 7'+0 lbs. per inch of soil (from line E) = inches need over <br /> tank cover. <br /> �S�� GDver HeedPW. <br />
