The pressure in the air column inside the pipe is the same regardless of the shape and dimensions of the pipe.

Is it?
I think the shape and dimension is a factor.
The bigger the shape, the more air displacement per linear measurement it will have as the water rises inside the tube.
Let's say 1cm of water rise in the tube of 1/4" will displace less air and create less pressure as oppose to a 2" tube.
Or am I not understanding this correctly.
Roberto.
