it would flow more easily through a narrow pipe
The open channel flow has a free or rather open surface whereas the pipe flow has a closed surface.
When a leak has occured in the pipe, or when there's to many twists and turns in the pipe, or when there's a blockage in the pipe.
Negative pressure
about 70 bar (1000 PSI)
The flow-line of a pipe is the bottom inside portion of the pipe. Flow-lines are generally reffered to when establishing the elevation of the pipe work.

of course liquid can flow through a pipe?

The open channel flow has a free surface whereas the pipe flow has a closed surface.
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.

A device for controlling the flow of liquid can sometimes be a pipe.
The open channel flow has a free or rather open surface whereas the pipe flow has a closed surface.
negative pressure is needed for a sustained flow of water in a pipe.
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.
