## How to Calculate and Solve for Water Distribution from Emitter | Irrigation Water Requirement

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 (Cvand 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
Cv = 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;

Cv = 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.
