Sprinkler and Micro Irrigation

In drip irrigation emission uniformity evaluation, the Emission Uniformity ($EU$) developed by Keller and Karmeli is:

Options:

• (A) $EU = 100 \left(1 - \frac{1.27 CV}{\sqrt{n}}\right) \frac{q_{min}}{q_{avg}}$
• (B) $EU = 100 \frac{q_{avg}}{q_{max}}$
• (C) $EU = 100 (1 - CV)$
• (D) $EU = 100 \frac{q_{min}}{q_{max}}$
