Section 5: Irrigation and Drainage Engineering

Irrigation Water Conveyance and Application Methods

Subtopic: Surface, sprinkler and micro irrigation methods

Question Statement:

In an orchard drip irrigation system, tree spacing is $6.0\text{ m} \times 6.0\text{ m}$. Each tree is provided with 4 drippers of $4.0\text{ L/h}$ discharge each. If the daily irrigation duration is $3.0\text{ hours}$, calculate the volume of water applied per tree per day in $\text{liters}$.

Answer Key:

48

Step-by-Step Solution & Explanation

Discharge rate per tree: $q_{\text{tree}} = 4 \times 4.0 = 16.0\text{ L/h}$ Volume applied in 3 hours: $V = 16.0\text{ L/h} \times 3.0\text{ h} = 48.0\text{ liters}$
