IrrigationQuestion 11 of 100
A drip emitter rated at 1 GPH means it delivers approximately how much water per hour?
a.1 gallon per hour
b.1 gallon per minute
c.60 gallons per hour
d.1 quart per day
Explanation
GPH stands for gallons per hour, so a 1 GPH emitter releases one gallon over a full hour of operation. Drip systems are rated in gallons per hour because they apply water slowly and precisely at the root zone. This low, slow application reduces runoff and evaporation.
