Here is how the Sewage Flow Rate equation looks like.

10 = \frac{(1.3 - 1.2) \cdot 100}{1.2 - 0.2}

10m³/s = \frac{(1.3 - 1.2) \cdot 100m³/s}{1.2 - 0.2}

10 = \frac{(1.3 - 1.2) \cdot 100}{1.2 - 0.2}

Sewage Flow Rate Solution

Follow our step by step solution on how to calculate Sewage Flow Rate?

FIRST Step Consider the formula

Q s = \frac{(C R - C) \cdot Q stream}{C - C s}

Next Step Substitute values of Variables

∴

Q s = \frac{(1.3 - 1.2) \cdot 100m³/s}{1.2 - 0.2}

Next Step Prepare to Evaluate

∴

Q s = \frac{(1.3 - 1.2) \cdot 100}{1.2 - 0.2}

LAST Step Evaluate

∴

Q s = 10m³/s

Go Sewage Concentration

C s = \frac{C \cdot (Q s + Q stream) - (C R \cdot Q stream)}{Q s}

Go River Stream Concentration

C R = \frac{C \cdot (Q s + Q stream) - (C s \cdot Q s)}{Q stream}

Go River Stream Flow Rate

Q stream = \frac{(C s \cdot Q s) - (C \cdot Q s)}{C - C R}

Go Mixing Concentration

C = \frac{C s \cdot Q s + C R \cdot Q stream}{Q s + Q stream}

How to Evaluate Sewage Flow Rate?

Sewage Flow Rate evaluator uses Sewage Discharge = ((River Concentration-Mixing Concentration)*Discharge in Stream)/(Mixing Concentration-Sewage Concentration) to evaluate the Sewage Discharge, The Sewage Flow Rate formula is defined as the volume of sewage passing through a system per unit time, usually expressed in liters per second (L/s), cubic meters per hour (m³/h), or million gallons per day (MGD). Sewage Discharge is denoted by Q_s symbol.

How to evaluate Sewage Flow Rate using this online evaluator? To use this online evaluator for Sewage Flow Rate, enter River Concentration (C_R), Mixing Concentration (C), Discharge in Stream (Q_stream) & Sewage Concentration (C_s) and hit the calculate button.

FAQs on Sewage Flow Rate

What is the formula to find Sewage Flow Rate?

The formula of Sewage Flow Rate is expressed as Sewage Discharge = ((River Concentration-Mixing Concentration)*Discharge in Stream)/(Mixing Concentration-Sewage Concentration). Here is an example- 6 = ((1.3-1.2)*100)/(1.2-0.2).

How to calculate Sewage Flow Rate?

With River Concentration (C_R), Mixing Concentration (C), Discharge in Stream (Q_stream) & Sewage Concentration (C_s) we can find Sewage Flow Rate using the formula - Sewage Discharge = ((River Concentration-Mixing Concentration)*Discharge in Stream)/(Mixing Concentration-Sewage Concentration).

Can the Sewage Flow Rate be negative?

No, the Sewage Flow Rate, measured in Volumetric Flow Rate cannot be negative.

Which unit is used to measure Sewage Flow Rate?

Sewage Flow Rate is usually measured using the Cubic Meter per Second[m³/s] for Volumetric Flow Rate. Cubic Meter per Day[m³/s], Cubic Meter per Hour[m³/s], Cubic Meter per Minute[m³/s] are the few other units in which Sewage Flow Rate can be measured.
