Hi everyone. So I currently have 3" aluminum irrigation pipe feeding a 1" main feed for my home irrigation. I want to eliminate the aluminum pipe and going to dig in a water line across my field.

The 3" aluminum pipe was about 65psi before changing to 1" but not sure about flow.

I want to run a 1.5" line in place of the 3" and then down to a 1" a little sooner. How can I determine if this will still be sufficient?

Thank you
