Al''s water analogy..

Water pressure in this case is a function ONLY of water depth. Two holes in
the bottom of a tank, assuming the same water depth above each hole, will
both be under the same water pressure, regardless of the size of the hole.
Two holes, of any size, located in the side of a tank at different depths
will exhibit different pressure. In an atmosheric-pressure system, the
pressure increases by one atmosphere (14 psi, I think) of pressure for
aproximately each 33 feet.
