Yes. The distance from the top surface of the reservoir to the discharge
opening determines the water pressure above atmospheric.

Subject: [elky] Way off topic...but sorta scientific: water pressure and flow
Fluid pressure. Does the pressure behind a fluid increase with the height of
its storage reservoir? I see lots of cities' water reservoirs in huge tanks
100 or so feet off the ground. Is this better than...say 20 feet higher than
the highest point in the town? If this is a law of physics, I don't know
it...and don't think I ever investigated this area before.
Here's the deal. We wanna test some fluid (we're gonna use colored water)
flowing thru a clear plastic pipe and I came up with one design, my partner
with another. His plan was to have 2 55 gallon drums mounted on a level
surface and "push" the fluid thru the tube with a sump pump and catch it in the
other. The pump pressure/volume is unknown at this time.
My plan was to mount the reservoir drum...say...6-10 feet higher than the
pipe and use a valve to control the flow into the pipe which would exit into
the catch drum; then use the sump pump to replenish the reservoir drum.
Is there any outstanding merit or disadvantage to either system (apart from
the fact that his way is easier to construct?)
Thanks,
