Lawn Nerds Sprinkler Repair & Maintenance

Ok. Here it goes.
I have a rotor that does it’s 180° sweep in 45sec.(one way)
The zones precipitation rate is .87 in/hr.
I have the duration of the zone set at 15mins.
How many inches of water does this sprinkler deliver during each scheduled run time?

P.S. I don’t know the answer. That’s why I’m posting this topic.

Thanks Lawn Nerds!

15min divided by 60min or 1hr =.25 x .87 in/hr = .2175 inches / 15 minute cycle

Nice. So that rotor isn’t doing enough and duh why didn’t I think of that? Thank you!

Yes catch can test. Efficiency is at something like 67%.
