I was thinking that too. He needs 12GPM, which isn't unusual, but
there are plenty of wells yielding less than that. It's worth
considering before scoping out the solution. He could also raise
the pressure up from 45 a bit too.

I thought it was six GPM, but it looks like it is Point Six (6/10) GPM.

That would be around 1.8 GPM for the 3 lines. Big difference. That is why
I would think he needs a larger line than the 1/2 inch he has, especially
for over 300 feet.

The way I read it, he has 20 drip lines each using .6 GPM. That's 12 GPM.
He could also put in a valve, either mechanical or automatic that would
only run some subset of those at a time.
