Water dynamics, well piping help...
I would like to pipe a water well ( using gravity alone) with a 250m run and an overall fall of 3m. A large barrier (a hill) is middle ways . The last 100m down the hill has most ,if not all the fall. The question is if I pipe this last 100m with a larger diameter (from 3/4" going to 1") would this increase the 'pull'/ 'suction'/ from the well and the pressure to the trough?
I have already been told the bigger pipe would cause less friction.
If force (gravity) is the same across both sections of pipe and so is the pressure then the volume of water in the smaller pipe would have to be greater? Yes?.....So I am thinking that more water will be sucked up higher on the small section by making the later section a larger diameter? Many thanks in advance!

You'll get the siphon effect only after you get the water over the highest point.

Thanks for reply, I will try to prime all the pipe.
