Here is how the Volume of Aerobic Digester equation looks like.

10.3344 = \frac{5 \cdot 5000.2}{0.014 \cdot ((0.05 \cdot 0.5) + 2)}

10.3344m³ = \frac{5m³/s \cdot 5000.2mg/L}{0.014mg/L \cdot ((0.05d⁻¹ \cdot 0.5) + 2d)}

10.3344 = \frac{5 \cdot 5000.2}{0.014 \cdot ((0.05 \cdot 0.5) + 2)}

Volume of Aerobic Digester Solution

Follow our step by step solution on how to calculate Volume of Aerobic Digester?

FIRST Step Consider the formula

V ad = \frac{Q i \cdot X i}{X \cdot ((K d \cdot P v) + θ)}

Next Step Substitute values of Variables

∴

V ad = \frac{5m³/s \cdot 5000.2mg/L}{0.014mg/L \cdot ((0.05d⁻¹ \cdot 0.5) + 2d)}

Next Step Convert Units

∴

V ad = \frac{5m³/s \cdot 5.0002kg/m³}{1.4E-5kg/m³ \cdot ((5.8E-7s⁻¹ \cdot 0.5) + 172800s)}

Next Step Prepare to Evaluate

∴

V ad = \frac{5 \cdot 5.0002}{1.4E-5 \cdot ((5.8E-7 \cdot 0.5) + 172800)}

Next Step Evaluate

∴

V ad = 10.3344080687658m³

LAST Step Rounding Answer

∴

V ad = 10.3344m³
