Stepping down the size of the pipe into a smaller one in fact WILL NOT GIVE MORE PRESSURE! The smaller the size of the pipe, the less water it can carry, and ultimatley distribute. So when you have multiple sprinkler heads, the feed lines are usually ran in 3/4 and the branch lines stepped down. Also the same with household cold water is always roughed in in 3/4 and stubbed out in 1/2. That's also why the city has a huge main feed and your house has only usually a 1"
the velocity of water flow within a drainage pipe; the equation is V=L/t L= Length t=time. Then the flow rate; Fr=A*V, Where A= sectional area and V = velocity.
it would flow more easily through a narrow pipe
Negative pressure
It wont unless its pressurized or under vaccuum.

That depends on the pressure behind the flow, and on the length of time the flow is allowed to continue.
Turbulent flow can increase a temp. to some extent
negative pressure is needed for a sustained flow of water in a pipe.

Yes, as long as the water coming out of the pipe has a greater pressure than the water that is covering the pipe. If it is the other way around, the water covering the pipe will actually flow into the pipe. Think about it. It just makes sense.

A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
It takes 24.50985 feet of 1 inch pipe to hold one gallon of water. Jeff Payne jpayne@texwipe.com
Depends on the pipe and the length but mostly the pressure stays the same but the flow will increase more speed.
Water flow rate half inch PVC pipe 65 psi?
You'll need the length of the pipe, because that's where the flow resistance is. At the outlet end, the pressure is atmospheric.
