Irrigation Water Conveyance and Application Methods
Subtopic: Surface, sprinkler and micro irrigation methods
Question Statement:
In a drip irrigation system, an emitter has a discharge exponent $x = 0.50$ and flow coefficient $k = 1.20$ in the equation $q = k H^x$ (where $q$ is in $\text{L/h}$ and $H$ is in meters). If the operating pressure head is $16.0\text{ m}$, the emitter discharge in $\text{L/h}$ is ________ (round off to 1 decimal place).
Answer Key:
4.8
Step-by-Step Solution & Explanation
Using the emitter discharge equation:
$q = k H^x = 1.20 \times (16.0)^{0.50} = 1.20 \times 4.0 = 4.80\text{ L/h}$
