Solving the equation of continuity given by the Laplace equation on the cylindrical coordinates, the mathematical solution for evaluating fluid pressure on rigid flat-bottom cylindrical shell tanks is derived. However, since difficulty of applying asymmetric boundary conditions on the cylindrical coordinates which trace realistic uplift motion of tanks restricts application of the preceding mathematical solution to the actual case scenario, the slice model consisting of a rigid rectangular tank with unit depth on a parallel plane to the uplift motion and offsetting from a center of tanks is developed. Comparison reveals applicability of the slice model for evaluating the fluid pressure on the rigid flat-bottom cylindrical rigid shell tanks.
