Diffusion Flux Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diffusion flux = Diffusion Coefficient*(Concentration difference/Distance)
J = D*(ΔC/d)
This formula uses 4 Variables

Variables Used

Diffusion flux - (Measured in Kilogram per Second per Square Meter) - Diffusion flux is the mass diffusing through and perpendicular to a unit cross-sectional area of solid per unit of time.
Diffusion Coefficient - (Measured in Square Meter Per Second) - Diffusion coefficient is the proportionality factor D in Fick's law .
Concentration difference - (Measured in Kilogram per Cubic Meter) - Concentration difference is the difference in concentration of diffusing species.
Distance - (Measured in Meter) - Distance (length) across which the diffusion is taking place.

STEP 1: Convert Input(s) to Base Unit

Diffusion Coefficient: 800 Square Meter Per Second --> 800 Square Meter Per Second No Conversion Required
Concentration difference: 0.5 Kilogram per Cubic Meter --> 0.5 Kilogram per Cubic Meter No Conversion Required
Distance: 0.01 Meter --> 0.01 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

J = D*(ΔC/d) --> 800*(0.5/0.01)

Evaluating ... ...

J = 40000

STEP 3: Convert Result to Output's Unit

40000 Kilogram per Second per Square Meter --> No Conversion Required

FINAL ANSWER

40000 Kilogram per Second per Square Meter <-- Diffusion flux
