Water Use Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Water Use Efficiency = (Quantity of Water used Beneficially/Quantity of water delivered to Field)*100
n_u = (W_u/W_f)*100
This formula uses 3 Variables

Variables Used

Water Use Efficiency - Water use efficiency is the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop.
Quantity of Water used Beneficially - (Measured in Liter per Second) - Quantity of water used beneficially the timing and total yield of water from a watershed.
Quantity of water delivered to Field - (Measured in Liter per Second) - Quantity of water delivered to field.

STEP 1: Convert Input(s) to Base Unit

Quantity of Water used Beneficially: 80 Liter per Second --> 80 Liter per Second No Conversion Required
Quantity of water delivered to Field: 110 Liter per Second --> 110 Liter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n_u = (W_u/W_f)*100 --> (80/110)*100

Evaluating ... ...

n_u = 72.7272727272727

STEP 3: Convert Result to Output's Unit

72.7272727272727 --> No Conversion Required

FINAL ANSWER

72.7272727272727 ≈ 72.72727 <-- Water Use Efficiency

What is Water-Use Efficiency in Irrigation?

In irrigation, Water Use Efficiency (WUE) represents the ratio between effective water use and actual water withdrawal. It characterizes, in a specific process, how effective is the use of water. Efficiency is scale and process dependent.

Why is Water-Use Efficiency important?

Efficient water use can have major environmental, public health, and economic benefits by helping to improve water quality, maintain aquatic ecosystems, and protect drinking water resources.

How to Calculate Water Use Efficiency?

Water Use Efficiency calculator uses Water Use Efficiency = (Quantity of Water used Beneficially/Quantity of water delivered to Field)*100 to calculate the Water Use Efficiency, The Water Use Efficiency formula is defined as the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop. Water Use Efficiency is denoted by n_u symbol.

How to calculate Water Use Efficiency using this online calculator? To use this online calculator for Water Use Efficiency, enter Quantity of Water used Beneficially (W_u) & Quantity of water delivered to Field (W_f) and hit the calculate button. Here is how the Water Use Efficiency calculation can be explained with given input values -> 72.72727 = (0.08/0.11)*100.
