Mixing Concentration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream)
C = (C_s*Q_s+C_R*Q_s)/(Q_s+Q_s)
This formula uses 5 Variables

Variables Used

Mixing concentration - Mixing concentration is the concentration obtained after sewage gets mixed in the river stream.
Sewage Concentration - Sewage Concentration can be in terms of bod, do, suspended solids etc.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage discharge is the flow rate of sewage when it is being discharged in the river.
River concentration - River concentration is the concentration of river parameters like bod, do etc.
Discharge in Stream - (Measured in Cubic Meter per Second) - Discharge in Stream is the volumetric flow rate of water that is transported through a given cross-sectional area.

STEP 1: Convert Input(s) to Base Unit

Sewage Concentration: 0.2 --> No Conversion Required
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
River concentration: 1.3 --> No Conversion Required
Discharge in Stream: 60 Cubic Meter per Second --> 60 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C = (C_s*Q_s+C_R*Q_s)/(Q_s+Q_s) --> (0.2*10+1.3*60)/(10+60)

Evaluating ... ...

C = 1.14285714285714

STEP 3: Convert Result to Output's Unit

1.14285714285714 --> No Conversion Required

FINAL ANSWER

1.14285714285714 ≈ 1.142857 <-- Mixing concentration

River Stream Flow Rate

Go Discharge in Stream = ((Sewage Concentration*Sewage Discharge)-(Mixing concentration*Sewage Discharge))/(Mixing concentration-River concentration)

River Stream Concentration

Go River concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(Sewage Concentration*Sewage Discharge))/Discharge in Stream

Sewage Concentration

Go Sewage Concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(River concentration*Discharge in Stream))/Sewage Discharge

Mixing Concentration

Go Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream)

Sewage Flow Rate

Go Sewage Discharge = ((River concentration-Mixing concentration)*Discharge in Stream)/(Mixing concentration-Sewage Concentration)

Actual DO

Go Actual Dissolved Oxygen = Saturated Dissolved Oxygen-Oxygen Deficit

Saturation DO

Go Saturated DO = Oxygen Deficit+Actual DO

Mixing Concentration Formula

Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream)
C = (C_s*Q_s+C_R*Q_s)/(Q_s+Q_s)

What is discharge?

Discharge is the amount of depth of water flow out from the river or reservoir in mm or litres with respect to time.

How to Calculate Mixing Concentration?

Mixing Concentration calculator uses Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream) to calculate the Mixing concentration, The Mixing Concentration is the concentration of the stream after the mixing of the stream and sewage took place. Mixing concentration is denoted by C symbol.

How to calculate Mixing Concentration using this online calculator? To use this online calculator for Mixing Concentration, enter Sewage Concentration (C_s), Sewage Discharge (Q_s), River concentration (C_R) & Discharge in Stream (Q_s) and hit the calculate button. Here is how the Mixing Concentration calculation can be explained with given input values -> 1.142857 = (0.2*10+1.3*60)/(10+60).

FAQ

What is Mixing Concentration?

The Mixing Concentration is the concentration of the stream after the mixing of the stream and sewage took place and is represented as C = (C_s*Q_s+C_R*Q_s)/(Q_s+Q_s) or Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream). Sewage Concentration can be in terms of bod, do, suspended solids etc, Sewage discharge is the flow rate of sewage when it is being discharged in the river, River concentration is the concentration of river parameters like bod, do etc & Discharge in Stream is the volumetric flow rate of water that is transported through a given cross-sectional area.

How to calculate Mixing Concentration?

The Mixing Concentration is the concentration of the stream after the mixing of the stream and sewage took place is calculated using Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream). To calculate Mixing Concentration, you need Sewage Concentration (C_s), Sewage Discharge (Q_s), River concentration (C_R) & Discharge in Stream (Q_s). With our tool, you need to enter the respective value for Sewage Concentration, Sewage Discharge, River concentration & Discharge in Stream and hit the calculate button.
