How do impact rotor nozzles work?

1. 1-2 nozzles are rotated by a spoon that pivots the nozzles in a circular pattern

2. Water is forced through a single fixed nozzle with high pressure

3. A fan-like device spreads water over a wide area

4. Multiple streams of water exit sequentially from each nozzle

The correct answer is: 1-2 nozzles are rotated by a spoon that pivots the nozzles in a circular pattern

Impact rotor nozzles function by utilizing a mechanism where one or two nozzles are rotated by a spoon-like component that causes the nozzles to pivot in a circular motion. This design enables the water to be distributed evenly over a larger area through the rotation of the nozzle, which creates a sweeping pattern of water application. This is particularly effective for watering large spaces, as the rotating nozzles allow for coverage of wider areas compared to stationary nozzles. The rotation and distribution method used in impact rotor nozzles is crucial for providing adequate coverage and ensuring that water reaches the intended areas efficiently. Understanding this mechanism is fundamental for effective irrigation practices, especially in landscape management.
