What is the flow rate range of dripline tubing?

• A. 1.5 - 2.0 GPH
• B. 0.26 - 1.0 GPH
• C. 2.0 - 3.5 GPH
• D. 0 - 0.25 GPH

Answer: (B)

Dripline tubing is specifically designed to deliver water directly to the root zone of plants, which helps in conserving water and improving irrigation efficiency. The flow rate range for standard drip irrigation systems typically falls between 0.26 to 1.0 gallons per hour (GPH). This flow rate is ideal for ensuring that water is applied slowly and evenly, allowing for adequate soil absorption and reducing the chance of runoff or over-saturation.

This range is suited for various landscaping applications, particularly in areas requiring efficient water use, such as arid regions or drought-prone environments. It helps maintain soil moisture while minimizing water waste, aligning with the principles of sustainable landscaping advocated by QWEL training.
