Average Daily Influent Flow Rate given Hydraulic Retention Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average daily influent flow rate = Reactor Volume/Hydraulic retention time
Q = V/θ
This formula uses 3 Variables

Variables Used

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.
Reactor Volume - (Measured in Cubic Meter) - The Reactor Volume gives us the capacity of the reactor.
Hydraulic retention time - (Measured in Second) - Hydraulic retention time defined as the ratio between the reactor volume and the feed flow rate, represents the average time the cells and substrates stay inside the reactor.

STEP 1: Convert Input(s) to Base Unit

Reactor Volume: 1000 Cubic Meter --> 1000 Cubic Meter No Conversion Required
Hydraulic retention time: 4 Hour --> 14400 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = V/θ --> 1000/14400

Evaluating ... ...

Q = 0.0694444444444444

STEP 3: Convert Result to Output's Unit

0.0694444444444444 Cubic Meter per Second -->6000 Cubic Meter per Day (Check conversion here)

FINAL ANSWER

6000 Cubic Meter per Day <-- Average daily influent flow rate

(Calculation completed in 00.020 seconds)
