Influent Flow Rate given Return Activated Sludge Flow Rate Solution

Follow our step by step solution on how to calculate Influent Flow Rate given Return Activated Sludge Flow Rate?

FIRST Step Consider the formula

Q = (\frac{RAS}{1.25})

Next Step Substitute values of Variables

∴

Q = (\frac{10m³/d}{1.25})

Next Step Convert Units

∴

Q = (\frac{0.0001m³/s}{1.25})

Next Step Prepare to Evaluate

∴

Q = (\frac{0.0001}{1.25})

Next Step Evaluate

∴

Q = 9.25925925925928E-05m³/s

Next Step Convert to Output's Unit

∴

Q = 8.00000000000002m³/d

LAST Step Rounding Answer

∴

Q = 8m³/d
