I'm looking some something like a dummies book or even less that deals
with some of the simpler (maybe) concepts of hydraulics. Maybe something
like hydraulics for plumbers or gardeners. Maybe something that answers
questions like if water is pumped out of a 2" pipe, which then splits
into two pipes, one is 1" and the other 1/2" in diameter, how much of
the water flows into each, or what, if any, pressure exists at the end
of each of the two pipes? If a 1" pipe is restricted to go into a 1/2"
pipe, how is the flow rate determined? Possibly there's 20 page or
whatever primer on the web of this sort?
