1. A flexible tank for transporting fluids in a transportation container, the flexible tank defining a tank volume for containing a fluid and comprising:
a mixing member enclosing a fluid pathway extending across an interior surface of the flexible tank, and
an inlet valve configured to allow passage of fluid from outside the flexible tank into the fluid pathway,
wherein the mixing member is conically or frustoconically shaped and reduces in cross sectional area along a longitudinal axis in a direction away from the inlet valve and includes an aperture such that the inlet valve is in fluid communication with the tank volume via the fluid pathway, and
wherein the mixing member comprises a plurality of apertures wherein the plurality of apertures include:
a proximate aperture, wherein the proximate aperture is a closest aperture of the plurality of apertures to the inlet valve;
an end aperture, wherein the end aperture is a farthest aperture of the plurality of apertures from the inlet valve; and
a plurality of middle apertures, wherein the plurality of middle apertures are larger than the proximate aperture and smaller than the end aperture.
