WAS Pumping Rate from Return Line given Wasting Rate from Return Line Solution

Follow our step by step solution on how to calculate WAS Pumping Rate from Return Line given Wasting Rate from Return Line?

FIRST Step Consider the formula

Q w = (V \cdot \frac{X}{θ c \cdot X r}) - (Q e \cdot \frac{X e}{X r})

Next Step Substitute values of Variables

∴

Q w = (1000m³ \cdot \frac{1200mg/L}{7d \cdot 200mg/L}) - (1523.81m³/d \cdot \frac{60mg/L}{200mg/L})

Next Step Convert Units

∴

Q w = (1000m³ \cdot \frac{1.2kg/m³}{604800s \cdot 0.2kg/m³}) - (0.0176m³/s \cdot \frac{0.06kg/m³}{0.2kg/m³})

Next Step Prepare to Evaluate

∴

Q w = (1000 \cdot \frac{1.2}{604800 \cdot 0.2}) - (0.0176 \cdot \frac{0.06}{0.2})

Next Step Evaluate

∴

Q w = 0.00462962797619048m³/s

Next Step Convert to Output's Unit

∴

Q w = 399.999857142858m³/d

LAST Step Rounding Answer

∴

Q w = 399.9999m³/d
