The future is save water and energy of irrigation pasture and crops.
Fields under 50 acres, solid set sprinkler irrigation or center pivot, both offer more savings (water and power).
A good irrigation project will consume 0.61 HP of energy per irrigated acre.
To know how much the operation of irrigation will be cost.
Imagine 25 acres, irrigated by sprinkler with flow up to 3,74 GPM.
The irrigation using a 7,5 HP Pumps.
Irrigation precipitation is 0,13" per hour.
We need irrigate around 4" of water per month or 0,13" every day on 25 acres,
The system irrigate 0,13" per hour with high water distribution.
If you irrigated 2.47 acre witch zone, the pumps will work 10 hours per day. independent of the irrigation cycle, which is the time between one irrigation and another.
And then, we have.
7.5 HP x 0,735 = 5,51 kw/hour.
5,51 kw/hour X 10 hours X 30 days per month = 1.653 kw of power to irrigate 24" of water per month.
Multiple 1.653 kw X kWh (our account power), maybe in Ohio is 0.13 USD per kWh.
1.653 kw X U$ 0,13 = U$ 214,00 divide by 25 acres = U$ 9,00 per acre irrigated only with power.
Keep calm, we have a goods news for America to irrigate pasture.
Is 5x cheaper than irrigation prices power in Brazil, but here we don't pay to use water, yet.
