Once you have the velocity of the water as it leaves the hole, plain old
highschool physics will give you the parabola.  The speed of the water would
be a function of the pressure and probably the diameter at small diameters.
I don't know how to compute that, but a few simple experiments should be
able to provide the answer relatively quickly.
