Question

Drip emitters can discharge water ranging from:

• A. 1 to 4 liters per hour
• B. 2 to 10 liters per hour
• C. 10 to 12 liters per hour
• D. 12 to 15 liters per hour

Hint:

Drip irrigation is characterized by low flow rates (liters per hour) and low operating pressures, distinguishing it from sprinkler systems which have much higher flow rates (liters per minute).

Answer 1

The Correct Option is B

Step 1: Understand the function of drip emitters. Drip emitters (or drippers) are devices used in drip irrigation systems to deliver water slowly and directly to the root zone of plants. Their purpose is to provide a low, controlled flow rate.
Step 2: State the typical discharge range for emitters. Emitters are manufactured with a variety of discharge rates to suit different soil types, plant needs, and system designs. The most common commercially available emitters have a discharge rate that typically falls within the range of 2 to 10 liters per hour (LPH). While rates as low as 1 LPH and slightly higher than 10 LPH exist, the 2-10 LPH range covers the vast majority of standard applications.
