You are correct, I should have said application rate, not coverage.
In one zone I placed six identical, numbered tuna cans evenly spaced within that 14' X 30' rectangular shaped area. I ran the the sprinkler for 30 minutes. I used a digital counting scale to measure the amount of water in each can and converted that to inches. The hourly result for each can was:
- 1.42"
- .92"
- .76"
- 1.44"
- 2.36"
- 2.22"
The cans were placed in the area so that 1 & 2 and 5 & 6 were at the ends, and 3 & 4 were in the middle.
