A rotor sprinkler head throwing water 30 feet is BEST described as which type of irrigation component?
a.A drip emitter for point-source watering
b.A gear-driven rotor for large turf areas
c.A micro-spray for shrub beds
d.A bubbler for tree wells
Giải thích
Gear-driven rotors rotate a single stream back and forth and are designed for large open turf areas because of their long throw radius, typically 25 to 50 feet. Drip emitters, micro-sprays, and bubblers all deliver water at much shorter ranges for beds, shrubs, or trees.
