Time given Organic Matter Present at Start of BOD Solution

Follow our step by step solution on how to calculate Time given Organic Matter Present at Start of BOD?

FIRST Step Consider the formula

t = - (\frac{1}{K D}) \cdot \log 10 (\frac{L t}{L s})

Next Step Substitute values of Variables

∴

t = - (\frac{1}{0.23d⁻¹}) \cdot \log 10 (\frac{0.21mg/L}{40mg/L})

Next Step Convert Units

∴

t = - (\frac{1}{2.7E-6s⁻¹}) \cdot \log 10 (\frac{0.0002kg/m³}{0.04kg/m³})

Next Step Prepare to Evaluate

∴

t = - (\frac{1}{2.7E-6}) \cdot \log 10 (\frac{0.0002}{0.04})

Next Step Evaluate

∴

t = 856427.113850979s

Next Step Convert to Output's Unit

∴

t = 9.9123508547567d

LAST Step Rounding Answer

∴

t = 9.9124d
