Consider the following configuration. We have an inverted (point down) right circular conical tank, with a top (base) radius R meters and a total height of H meters, filled with water to a height of h meters.

There is a circular hole of radius rC meters at the very bottom of the cone from where water flows out of the cone.

This water falls into an open-topped cubicle tank sitting directly below the cone.

Finally, this cubicle tank also has a circular hole at the center of its base with radius rB meters and water flows out of the bottom cubicle tank.
