How to Calculate and Solve for Water Convergence efficiency | Methods of Application of Water

Last Updated on September 30, 2020

The image above represents water convergence efficiency.

To compute for water convergence efficiency, two essential parameters are needed and these parameters are Water delivered to the Irrigated Plot (wfand Water delivered from the Source (wd).

The formula for calculating water convergence efficiency:

Ec = 100 . wf / wd

Where:

Ec = Water Convergence Efficiency
wf = Water delivered to the Irrigated Plot
wd = Water delivered from the Source

Let’s solve an example;
Find the water convergence efficiency when the water delivered to the irrigated plot is 30 and the water delievered from the source is 10.

This implies that;

wf = Water delivered to the Irrigated Plot = 30
wd = Water delivered from the Source = 10

Ec = 100 . wf / wd
Ec = 100 . (30) / 10
Ec = 3000 / 10
Ec = 300

Therefore, the water convergence efficiency is 300%.

Calculating the Water Delivered to the Irrigated Plot when the Water Convergence Efficiency and the Water Delivered from the Source is Given.

wf = Ec x wd / 100

Where;

wf = Water delivered to the Irrigated Plot
Ec = Water Convergence Efficiency
wd = Water delivered from the Source

Let’s solve an example;
Find the water delivered to the irrigated plot when the water convergence efficiency is 20 and the water delivered from the source is 5.

This implies that;

Ec = Water Convergence Efficiency = 20
wd = Water delivered from the Source = 5

wf = Ec x wd / 100
wf = 20 x 5 / 100
wf = 100 / 100
wf = 1

Therefore, the water delivered to the irrigated plot is 1%.

Calculating the Water Delivered from the Source when the Water Convergence Efficiency and the Water Delivered to the Irrigated Plot is Given.

wd = 100 x wf / Ec

Where;

wd = Water delivered from the Source
Ec = Water Convergence Efficiency
wf = Water delivered to the Irrigated Plot

Let’s solve an example;
Find the water delivered from the source when the water convergence efficiency is 40 and the water delivered to the irrigated plot is 20.

This implies that;

Ec = Water Convergence Efficiency = 40
wf = Water delivered to the Irrigated Plot = 20

wd = 100 x wf / Ec
wd = 100 x 20 / 40
wd = 2000 / 40
wd = 50

Therefore, the water delivered from the source is 50%.
