LTi //11 � Q e� SPer9er <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 /> 0 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 l 3 — `/9y�� <br /> 8 _�. , T_ inches Long, — cubic inches. <br /> ids <br /> Divide this number by 1728 to equal cubic feet. <br /> Line B Next convert the displacement to the weight of water. <br /> �? a (from line A) cubic feet x 62.4 (weight of 1 cubic foot of water) x 1.5 (fudge factor) _ <br /> j 57A .;Z7CSo lbs of lift potential. <br /> Line C Calculate weight needed to counter buoyancy. <br /> �?7e-'b lbs. (Displacement weight from line B.) -//01° lbs. (weight of tank from <br /> manufacture) = lbs. Of soil needed to anchor tanky/ o to'V # 7�2 <br /> Line D Weight over the tank cover needed,plus safety factor. <br /> 7:_inches wide of tank cover x /inches long of tank cover, divided by 144 <br /> y ,; Square feet of cover x 0.083 ( 1 inch in foot decimal)_ 7,q cubic foot space of <br /> 1 inch of tank cover. 3-- 7 <br /> Line E Calculated weight of 1 inch of space over entire cover. <br /> .77 U <br /> '3, <br /> t i cubic feet of space ( from lino D) x 100 lbs./cubic foot of= 7 yo lbs./inch space above <br /> cover. <br /> Line F Calculate inches of soil needed to counter buoyancy . <br /> POPS C lbs. (from line C) divided by /Zy lbs. per inch of soil (from line E) =inches need over <br /> tank cover. <br />
