The Pressure Of Water
The pressure of water may be known to every one who will only take the
trouble to look at the cock of a water-butt when turned: if the tub or
cistern be full, the water runs with much greater velocity through
the cock, and a vessel will be filled from it in a shorter time than
when it is only half-full, although the cock, in both cases, is
equally replete with the fluid during the time the vessel is filling.
From this also is understood, how a hole or leak, near the keel of a
ship, admits the water much quicker, and with greater violence, than
one of the same size near what the mariners call the water's edge.
