# Flow of fluids

Two identical barrels are filled with the same volume of water. The barrels have identical holes in their bottoms (which begin plugged) but barrel A also has one in its top (which is always open).

At time zero, the plugs are removed and the water starts to flow out of the bottom, as shown in the figure.

Which barrel will empty first?

Assume that the holes are the same size and shape.
