Detention Time for Rectangular Tank Solution

STEP 0: Pre-Calculation Summary

Formula Used

Detention Time = Volume of Tank/Discharge in Tank
T_d = V/Q_d
This formula uses 3 Variables

Variables Used

Detention Time - (Measured in Second) - Detention Time is the length of time the water is retained in a vessel or basin.
Volume of Tank - (Measured in Cubic Meter) - Volume of Tank is defined as the capacity of flocculation and mixing tank.
Discharge in Tank - (Measured in Cubic Meter per Second) - Discharge in Tank is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material.

STEP 1: Convert Input(s) to Base Unit

Volume of Tank: 55.98 Cubic Meter --> 55.98 Cubic Meter No Conversion Required
Discharge in Tank: 8.2 Cubic Meter per Second --> 8.2 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_d = V/Q_d --> 55.98/8.2

Evaluating ... ...

T_d = 6.82682926829268

STEP 3: Convert Result to Output's Unit

6.82682926829268 Second --> No Conversion Required

FINAL ANSWER

6.82682926829268 ≈ 6.826829 Second <-- Detention Time

(Calculation completed in 00.004 seconds)

Overflow Rate given Discharge

Go Overflow Rate = Discharge/(Width*Length)

Cross-section Area of Tank with known Velocity of Flow of Water

Go Cross-Sectional Area = Discharge/Velocity of Flow of Water

Rate of Flow given Detention Time

Go Rate of Flow = (Volume of Tank/Detention Time)

Volume of Tank given Detention Time

Go Volume of Tank = Detention Time*Rate of Flow

Detention Time for Rectangular Tank Formula

Detention Time = Volume of Tank/Discharge in Tank
T_d = V/Q_d

What is Detention Time?

Detention time is a measure of how long a given molecule of water resides within a pond before being discharged.

How to Calculate Detention Time for Rectangular Tank?

FAQ

What is Detention Time for Rectangular Tank?

The Detention Time for Rectangular Tank is defined as theoretical time required for given amount of water or wastewater to pass through rectangular shaped tank at given rate of flow and is represented as T_d = V/Q_d or Detention Time = Volume of Tank/Discharge in Tank. Volume of Tank is defined as the capacity of flocculation and mixing tank & Discharge in Tank is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material.

How to calculate Detention Time for Rectangular Tank?

The Detention Time for Rectangular Tank is defined as theoretical time required for given amount of water or wastewater to pass through rectangular shaped tank at given rate of flow is calculated using Detention Time = Volume of Tank/Discharge in Tank. To calculate Detention Time for Rectangular Tank, you need Volume of Tank (V) & Discharge in Tank (Q_d). With our tool, you need to enter the respective value for Volume of Tank & Discharge in Tank and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Detention Time?

In this formula, Detention Time uses Volume of Tank & Discharge in Tank. We can use 2 other way(s) to calculate the same, which is/are as follows -

Detention Time = ((Width*Length*Depth)/Discharge)
Detention Time = ((Diameter)^2)*(((0.011*Diameter)+(0.785*Depth))/Discharge in Tank)
