Here is how the Diffusion Coefficient equation looks like.

3.15 = 0.6 \cdot \frac{17 + 4}{4}

3.15 = 0.6 \cdot \frac{17m + 4m}{4m}

3.15 = 0.6 \cdot \frac{17 + 4}{4}

Diffusion Coefficient Solution

Follow our step by step solution on how to calculate Diffusion Coefficient?

FIRST Step Consider the formula

D 0 = D \cdot \frac{x + B}{B}

Next Step Substitute values of Variables

∴

D 0 = 0.6 \cdot \frac{17m + 4m}{4m}

Next Step Prepare to Evaluate

∴

D 0 = 0.6 \cdot \frac{17 + 4}{4}

LAST Step Evaluate

∴

D 0 = 3.15

How to Evaluate Diffusion Coefficient?

Diffusion Coefficient evaluator uses Diffusion Coefficient at x = Apparent Dispersion Coefficient*(Coordinate along the Channel+Distance Outside the Estuary)/Distance Outside the Estuary to evaluate the Diffusion Coefficient at x=0, The Diffusion Coefficient formula is determined when the salinity matches that of the ocean, affecting the extreme salinity distribution (maximum and minimum intrusion) during moments of slack water. Diffusion Coefficient at x=0 is denoted by D₀ symbol.

How to evaluate Diffusion Coefficient using this online evaluator? To use this online evaluator for Diffusion Coefficient, enter Apparent Dispersion Coefficient (D), Coordinate along the Channel (x) & Distance Outside the Estuary (B) and hit the calculate button.

FAQs on Diffusion Coefficient

What is the formula to find Diffusion Coefficient?

The formula of Diffusion Coefficient is expressed as Diffusion Coefficient at x = Apparent Dispersion Coefficient*(Coordinate along the Channel+Distance Outside the Estuary)/Distance Outside the Estuary. Here is an example- 3.15 = 0.6*(17+4)/4.

How to calculate Diffusion Coefficient?

With Apparent Dispersion Coefficient (D), Coordinate along the Channel (x) & Distance Outside the Estuary (B) we can find Diffusion Coefficient using the formula - Diffusion Coefficient at x = Apparent Dispersion Coefficient*(Coordinate along the Channel+Distance Outside the Estuary)/Distance Outside the Estuary.
