Increase the pressure.'
ABSOLUTELY WRONG.Pressure cannot be increase by reducing a pipe diameter.If you have 60 PSI Flowing thought 2" pipe and decrease the pipe to 1" you still have the same 60 PSI supply pressure.
If the above lie was true then why not have the city main be 60" pipe reduce it to 2" to give "pressure" to 47 high rises?
What is actually happening your INCREASING VELOCITY LOWERING Volume and doing NOTHING but possibly lowering the pressures do to friction losses
it would flow more easily through a narrow pipe
Water will flow more easily through a wide pipe than a narrow pipe. This is because a wider pipe offers less resistance to the flow, allowing a greater volume of water to pass through simultaneously. In contrast, a narrow pipe restricts the flow, creating higher pressure and turbulence, which can impede the movement of water. Therefore, the diameter of the pipe significantly affects the flow rate.
If water is flowing through pipe, no head pressure can build up. Blocking off flow of water will create head pressure in pipe as long as pipe is vertical. A vertical column of water creates head pressure.
Negative pressure
it takes the same pressure if the vertical heights the same but since the 45 degree pipe would be longer it would create more flow restriction.
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.
it would flow more easily through a narrow pipe
Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.
negative pressure is needed for a sustained flow of water in a pipe.
More, depending on how long you allow the flow to flow.
That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
Insufficient information, one needs to know the pressure of the water entering the pipe, the relative heights of both ends the pipe, the pressure of the water at the discharge of the pipe, the geometry of the pipe including the number and types of turns, and the pipe material or internal friction coefficient. Then you can calculate the flow.

In an electrical circuit, resistance is like the narrowness of a pipe that restricts the flow of water. Just as resistance limits the flow of electricity in a circuit, a narrow pipe restricts the flow of water. Both resistance and a narrow pipe cause a decrease in the flow rate.
No, water cannot flow uphill in a pipe without the assistance of a pump or other external force.
A pressure difference between two points along the pipe is necessary for the sustained flow of water. This pressure difference creates a driving force that pushes the water through the pipe, overcoming frictional resistance and allowing for continuous flow.
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.
