Need help on irrigation planning
So I have this system design for PVC based irrigation system. The mainline is 2 inch PVC with T's every 10ft or so for 3/4 inch (garden hose) connections.
The 3/4 inch need to be at least 20 psi each, but I'd rather have them at 25-30 psi.
So here's my question: How many psi do I need on the mainline to run all 20 3/4 inch T's at once??
