1" Pipe capacity.

I am installing a lake pump up rather a very tall and long hill. We have been experiencing alot of rain this summer and if I open trench I do not want have erosion issues. So instead of open trenching a 1.5" pvc pipe I thought about pulling/plowing in 2 1" poly pipes. I looked at flow charts of 1" pipe at 5fps and it gave me 12 gpm In theory wouldnt 2 1" pipes be the same as a 2" pipe? Or will that theory only apply if the 1" pipe is looped/in a circle?

2" pipe can carry more than triple of a 1" pipe. Why not pull a 1.5" pipe or 2"

Even my old Pipe Piper could pull 1-1/4 inch poly, so any "real" plow should handle 1-1/2 inch at the very least.

My Zahn can pull 2" quite easily, with the correct bullet.
