Let's say water is flowing from an arbitrary
Source to some arbitrary
Sink via a small pipe:
I'm curious as to what actually happens when we change the diameter of the pipe:
If all other things are held constant, does the speed of the water increase through the pipe increase, or does only the volume increase?
BTW, this is not homework I'm a 30-yr old software developer/homeowner trying to figure out a problem with my plumbing.
