Water Use Efficiency Solution

Follow our step by step solution on how to calculate Water Use Efficiency?

FIRST Step Consider the formula

n u = (\frac{W u}{W f}) \cdot 100

Next Step Substitute values of Variables

∴

n u = (\frac{80L/s}{110L/s}) \cdot 100

Next Step Prepare to Evaluate

∴

n u = (\frac{80}{110}) \cdot 100

Next Step Evaluate

∴

n u = 72.7272727272727

LAST Step Rounding Answer

∴

n u = 72.7273
