Oxygen Deficit Solution

STEP 0: Pre-Calculation Summary

Formula Used

Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen
D = S_DO-A_DO
This formula uses 3 Variables

Variables Used

Oxygen Deficit - (Measured in Kilogram per Cubic Meter) - Oxygen Deficit is defined as the sum of the minute differences between the measured oxygen uptake and the oxygen uptake occurring during steady-state work at that same rate.
Saturated Dissolved Oxygen - (Measured in Kilogram per Cubic Meter) - Saturated Dissolved Oxygen is the dissolved oxygen present in the water at permissible limit.
Actual Dissolved Oxygen - (Measured in Kilogram per Cubic Meter) - Actual Dissolved Oxygen is the amount of dissolved oxygen present in the water.

STEP 1: Convert Input(s) to Base Unit

Saturated Dissolved Oxygen: 9 Milligram per Liter --> 0.009 Kilogram per Cubic Meter (Check conversion here)
Actual Dissolved Oxygen: 6.5 Milligram per Liter --> 0.0065 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = S_DO-A_DO --> 0.009-0.0065

Evaluating ... ...

D = 0.0025

STEP 3: Convert Result to Output's Unit

0.0025 Kilogram per Cubic Meter -->2.5 Milligram per Liter (Check conversion here)

FINAL ANSWER

2.5 Milligram per Liter <-- Oxygen Deficit

(Calculation completed in 00.004 seconds)

< 5 Oxygen Deficit Calculators

DO Deficit using Streeter-Phelps Equation

Go Oxygen Deficit = (Deoxygenation Constant*Organic Matter at Start/(Reoxygenation coefficient-Deoxygenation Constant))*(10^(-Deoxygenation Constant*Time in days)-10^(-Reoxygenation coefficient*Time in days)+Initial oxygen deficit*10^(-Reoxygenation coefficient*Time in days))

Initial Oxygen Deficit in First Stage Equation

Go Initial oxygen deficit = 1-(((1/Critical oxygen deficit)^(Self purification constant-1))*((Oxygen Equivalent/Self purification constant)^Self purification constant)/(Self purification constant-1))

Oxygen Deficit given Critical Time in Self Purification Factor

Go Critical oxygen deficit = (Oxygen Equivalent/(Self purification constant-1))*(1-((10^(Critical time*Deoxygenation Constant*(Self purification constant-1)))/Self purification constant))

Log value of Critical Oxygen Deficit

Go Critical oxygen deficit = 10^(log10(Oxygen Equivalent/Self purification constant)-(Deoxygenation Constant*Critical time))

Oxygen Deficit

Go Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen

Oxygen Deficit Formula

Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen
D = S_DO-A_DO

What is DO?

Dissolved Oxygen is the amount of gaseous oxygen (O2) dissolved in the water. Oxygen enters the water by direct absorption from the atmosphere, by rapid movement, or as a waste product of plant photosynthesis.

How to Calculate Oxygen Deficit?

Oxygen Deficit calculator uses Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen to calculate the Oxygen Deficit, The Oxygen Deficit is the difference between the actual DO content of water at that time and the saturated DO content. Oxygen Deficit is denoted by D symbol.

How to calculate Oxygen Deficit using this online calculator? To use this online calculator for Oxygen Deficit, enter Saturated Dissolved Oxygen (S_DO) & Actual Dissolved Oxygen (A_DO) and hit the calculate button. Here is how the Oxygen Deficit calculation can be explained with given input values -> 2500 = 0.009-0.0065.

FAQ

What is Oxygen Deficit?

The Oxygen Deficit is the difference between the actual DO content of water at that time and the saturated DO content and is represented as D = S_DO-A_DO or Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen. Saturated Dissolved Oxygen is the dissolved oxygen present in the water at permissible limit & Actual Dissolved Oxygen is the amount of dissolved oxygen present in the water.

How to calculate Oxygen Deficit?

The Oxygen Deficit is the difference between the actual DO content of water at that time and the saturated DO content is calculated using Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen. To calculate Oxygen Deficit, you need Saturated Dissolved Oxygen (S_DO) & Actual Dissolved Oxygen (A_DO). With our tool, you need to enter the respective value for Saturated Dissolved Oxygen & Actual Dissolved Oxygen 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 Oxygen Deficit?

In this formula, Oxygen Deficit uses Saturated Dissolved Oxygen & Actual Dissolved Oxygen. We can use 1 other way(s) to calculate the same, which is/are as follows -

Oxygen Deficit = (Deoxygenation Constant*Organic Matter at Start/(Reoxygenation coefficient-Deoxygenation Constant))*(10^(-Deoxygenation Constant*Time in days)-10^(-Reoxygenation coefficient*Time in days)+Initial oxygen deficit*10^(-Reoxygenation coefficient*Time in days))
