A tank, in the shape of a rectangular cuboid, has inside it two vertical partitions fixed to its base and two opposite walls, being perpendicular to them, as shown in the figure.
These partitions, of negligible thickness, are installed so as to divide the base of the tank into three congruent rectangles, with heights equal to half and one-fourth of the tank's height. The tank is filled through an inlet located on the roof, via a pipe pouring water at a constant flow rate, taking 12 hours to complete its filling.
The graph that describes, at each moment, the maximum water column height among those formed throughout the filling of the tank, is
Graph linearly increasing from 0 h to 2 h, constant from 2 h to 4 h, and linearly increasing from 4 h to 12 h.
Graph linearly increasing from 0 h to 2 h, constant from 2 h to 6 h, and linearly increasing from 6 h to 12 h.
Graph linearly increasing from 0 h to 2 h, constant from 2 h to 10 h, and linearly increasing from 10 h to 12 h.
Step graph with discontinuities: from 0 h to 2 h at an intermediate height, from 2 h to 4 h at a lower level, from 4 h to 6 h at the intermediate level, and from 6 h to 10 h at the top level.
