Fluid storage tank comprising: a plurality of tank subunits (20, 20 ', 20'') arranged in a group (40, 40'), wherein: each tank subunit (20, 20 ', 20'') of the plurality of tank subunits (20, 20', 20 '') has an aperture (34) defined in at least one wall and another aperture (Fig. 34) defined in at least one adjacent tank subunit (20, 20 ', 20'') of the plurality of tank subunits (20, 20', 20 ''); each tank subassembly (20, 20 ', 20'') of the plurality of tank subunits (20, 20', 20 '') is in fluid communication with a single outlet port (38) for selectively removing the fluid from the tank; each tank subassembly (20, 20 ', 20 ") of the plurality of tank subunits (20, 20', 20") is in fluid communication with a single fluid fill port (39); each tank subassembly (20, 20 ', 20 ") has an internal volume ranging from about 0.2 liters to about 3.0 liters; each tank subassembly (20, 20 ', 20 ") of the plurality of tank subunits (20, 20', 20") has substantially the same shape and external size; and a first tank subunit (20, 20 ', 20'') of the plurality of tank subunits (20, 20', 20 '') is formed of a first material and a second tank subunit (20, 20 ', 20 '') of the plurality of tank subunits (20, 20 ', 20'') is formed of a second material, wherein a yield strength of the first material is higher than a yield strength of the second material; in which: one surface of the at least one tank subunit (20, 20 ', 20'') has a wall thickness greater than that of the other surface of the at least one tank subunit (20, 20', 20 ''); an area of the at least one tank subunit (20, 20 ', 20'') is formed of a material having a yield strength higher than the yield strength of another material that is adjacent to another surface of the at least one tank subunit (20, 20 ', 20'') is formed; ... |
