Here is how the Oxygen Deficit equation looks like.

4.2 = 9 - 4.8

4.2mg/L = 9mg/L - 4.8mg/L

4.2 = 9 - 4.8

Oxygen Deficit Solution

Follow our step by step solution on how to calculate Oxygen Deficit?

FIRST Step Consider the formula

D = S DO - A DO

Next Step Substitute values of Variables

∴

D = 9mg/L - 4.8mg/L

Next Step Convert Units

∴

D = 0.009kg/m³ - 0.0048kg/m³

Next Step Prepare to Evaluate

∴

D = 0.009 - 0.0048

Next Step Evaluate

∴

D = 0.0042kg/m³

LAST Step Convert to Output's Unit

∴

D = 4.2mg/L

D c = (\frac{L t}{f - 1}) \cdot (1 - (\frac{10^{t c \cdot K D \cdot (f - 1)}}{f}))

How to Evaluate Oxygen Deficit?

Oxygen Deficit evaluator uses Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen to evaluate the Oxygen Deficit, The Oxygen Deficit formula is defined as the difference between the saturation concentration of dissolved oxygen (DO) and the actual concentration of DO present in the water. Oxygen Deficit is denoted by D symbol.

How to evaluate Oxygen Deficit using this online evaluator? To use this online evaluator for Oxygen Deficit, enter Saturated Dissolved Oxygen (S_DO) & Actual Dissolved Oxygen (A_DO) and hit the calculate button.

FAQs on Oxygen Deficit

What is the formula to find Oxygen Deficit?

The formula of Oxygen Deficit is expressed as Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen. Here is an example- 2500 = 0.009-0.0048.

How to calculate Oxygen Deficit?

With Saturated Dissolved Oxygen (S_DO) & Actual Dissolved Oxygen (A_DO) we can find Oxygen Deficit using the formula - Oxygen Deficit = Saturated Dissolved Oxygen-Actual Dissolved Oxygen.

What are the other ways to Calculate Oxygen Deficit?

Here are the different ways to Calculate Oxygen Deficit-

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))

Can the Oxygen Deficit be negative?

No, the Oxygen Deficit, measured in Density cannot be negative.

Which unit is used to measure Oxygen Deficit?

Oxygen Deficit is usually measured using the Milligram per Liter[mg/L] for Density. Kilogram per Cubic Meter[mg/L], Kilogram per Cubic Centimeter[mg/L], Gram per Cubic Meter[mg/L] are the few other units in which Oxygen Deficit can be measured.
