Tank Anchoring: Per Comm 83.43(8)(g), Wis. Adm. Code,all tank(s)most be anchored <br /> whenever they are at risk for being installed in an area where they may be located in saturated <br /> conditions all/part of the year. Using soil as the anchor has become an acceptable alternative to <br /> 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 /> b643p� <br /> 6S inches high, x 70 inches wide, x I N6 _inches long, = cubic inches. <br /> Divide this number by 1728 to equal 387 cubic feet. <br /> Line B: Convert the displacement to the weight of water. <br /> V q (from line A) cubic feet x 624(weight of I cubic foot of water) x 1.5(safety factor) _ <br /> 3697(�Ibs. of lift potential. <br /> Mue C: Calculate weight needed to counter buoyancy. <br /> 357712 lbs.
