Average Daily Influent Flow Rate given Theoretical Oxygen Requirement Solution

Follow our step by step solution on how to calculate Average Daily Influent Flow Rate given Theoretical Oxygen Requirement?

FIRST Step Consider the formula

Q a = (O 2 + (1.42 \cdot P x)) \cdot (\frac{f}{8.34 \cdot (S o - S)})

Next Step Substitute values of Variables

∴

Q a = (2.5mg/d + (1.42 \cdot 20mg/d)) \cdot (\frac{0.68}{8.34 \cdot (25mg/L - 15mg/L)})

Next Step Convert Units

∴

Q a = (2.9E-11kg/s + (1.42 \cdot 2.3E-10kg/s)) \cdot (\frac{0.68}{8.34 \cdot (0.025kg/m³ - 0.015kg/m³)})

Next Step Prepare to Evaluate

∴

Q a = (2.9E-11 + (1.42 \cdot 2.3E-10)) \cdot (\frac{0.68}{8.34 \cdot (0.025 - 0.015)})

Next Step Evaluate

∴

Q a = 2.916000532907E-09m³/s

Next Step Convert to Output's Unit

∴

Q a = 0.000251942446043165m³/d

LAST Step Rounding Answer

∴

Q a = 0.0003m³/d
