The image above represents water distribution from emitter.

To compute for water distribution from emitter,two essential parameters are needed and these parameters are **Manufacturer’s Co-efficient of Variation (C _{v}) **and

**Number of Emitters per Plant (n).**

The formula for calculating water distribution from emitter:

EU = 1 – [^{0.8Cv} / _{n0.5}]

Where:

EU = Water Distribution from Emitter

C_{v} = Manufacturer’s Co-efficient of Variation

n = Number of Emitters per Plant

Let’s solve an example;

Find the water distribution from emitter when the manufacturer’s co-efficient of variation is 27 and number of emitters per plant is 3.

This implies that;

C_{v} = Manufacturer’s Co-efficient of Variation = 27

n = Number of Emitters per Plant = 3

EU = 1 – [^{0.8Cv} / _{n0.5}]

EU = 1 – [^{0.8(27)} / _{(3)0.5}]

EU = 1 – [^{21.6} / _{1.732}]

EU = 1 – [12.47]

EU = -11.47

Therefore, the **water distribution from emitter **is **-11.47.**
