Ratio of BOD to Ultimate BOD Solution

Follow our step by step solution on how to calculate Ratio of BOD to Ultimate BOD?

FIRST Step Consider the formula

f = \frac{BOD 5}{BOD u}

Next Step Substitute values of Variables

∴

f = \frac{6mg/L}{2mg/L}

Next Step Convert Units

∴

f = \frac{0.006kg/m³}{0.002kg/m³}

Next Step Prepare to Evaluate

∴

f = \frac{0.006}{0.002}

LAST Step Evaluate

∴

f = 3
