The image above represents water distribution from the emitter. To calculate water distribution from the emitter,two essential parameters are needed: the Manufacturer’s Co-efficient of Variation (Cv) and the 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)Â /Â (3)0.5]
So, EU = 1 – [21.6Â /Â 1.732]
EU = 1 – [12.47]
EU = -11.47
Therefore, the water distribution from emitter is -11.47.
