gravity
ANS 2 -gravity will only work if you're downhill from supply. -You may have to fit a 'booster' pump.
pressure gradient
Root pressure tries to keep the water flowing but transpiration loses water from the leaves
The internal pressure decreases as can be deducted from the Bernoulli equation P + 0.5 (d) (v)^2 + (d)(g)(h) = constant in a streamlined flow, where d = density. When v increases, P decreases as h = height, is constant.
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
A faucet and spray paint unfortunately I can't think of a third one I hope this helps though!
To increase the exhaust velocity. +++ Pressure, not velocity. A gas flowing through a divergent nozzle gains pressure at the cost of speed.
There really isn't any statistics. A naturally flowing well must have a well head pressure sufficiently above atmospheric to be able to flow into the separator. A well under natural pressure depletion and flowing conditions will have a declining wellhead pressure, but if artificial lift is installed, the well head pressure can markedly increase.
Nope. The blood pressure actually decreases when your heart relaxes. Although the heart relaxes, it is still in pressure or else your blood would stop flowing which to some people is a bad thing.

Water flowing out of the ground is a spring. An artesian well is one example of water under pressure flowing out of the ground.
pressure gradient
yes
It doesn't. The opposite is true. Blood pressure is proportional to blood volume. The greater the blood volume is, the higher the blood pressure will be. This is because there will be a greater volume of blood flowing through the blood vessels which means that a greater pressure will be exerted on the walls of the blood vessels, which means increased blood pressure.
The energy behind a fire hydrant that is not flowing water is known as "static pressure". This is the water pressure that is normally available from the water main when the hydrant is closed.
the pressure whose pressure is to be calculated is flowing agaunst gravity
