Observed Cell Yield given Net Waste Activated Sludge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Observed Cell Yield = Net waste activated sludge/(8.34*Average daily influent flow rate*(Influent Substrate Concentration-Effluent substrate concentration))
Y_obs = P_x/(8.34*Q*(S_o-S))
This formula uses 5 Variables

Variables Used

Observed Cell Yield - Observed Cell Yield is the observed mg of cells produced per mg organic matter removed.
Net waste activated sludge - (Measured in Kilogram per Second) - Net waste activated sludge is the amount of waste product that can be treated using the activated sludge process.
Average daily influent flow rate - (Measured in Cubic Meter per Second) - Average daily influent flow rate is the total discharge that comes in the reactor.
Influent Substrate Concentration - (Measured in Kilogram per Cubic Meter) - Influent Substrate Concentration is the concentration of BOD that is present in the influent.
Effluent substrate concentration - (Measured in Kilogram per Cubic Meter) - Effluent substrate concentration is the concentration of the BOD present in the effluent.

STEP 1: Convert Input(s) to Base Unit

Net waste activated sludge: 20 Milligram per Day --> 2.31481481481481E-10 Kilogram per Second (Check conversion here)
Average daily influent flow rate: 1.2 Cubic Meter per Day --> 1.38888888888889E-05 Cubic Meter per Second (Check conversion here)
Influent Substrate Concentration: 25 Milligram per Liter --> 0.025 Kilogram per Cubic Meter (Check conversion here)
Effluent substrate concentration: 15 Milligram per Liter --> 0.015 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Y_obs = P_x/(8.34*Q*(S_o-S)) --> 2.31481481481481E-10/(8.34*1.38888888888889E-05*(0.025-0.015))

Evaluating ... ...

Y_obs = 0.000199840127897681

STEP 3: Convert Result to Output's Unit

0.000199840127897681 --> No Conversion Required

FINAL ANSWER

0.000199840127897681 ≈ 0.0002 <-- Observed Cell Yield
