Diffusion Coefficient given Standard Deviation Solution

STEP 0: Pre-Calculation Summary
Formula Used
Diffusion Coefficient = ((Standard Deviation)^2)/(2*Time for diffusion)
D = ((σ)^2)/(2*t)
This formula uses 3 Variables
Variables Used
Diffusion Coefficient - (Measured in Square Meter Per Second) - Diffusion coefficient is the proportionality factor D in Fick's law .
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.
Time for diffusion - (Measured in Second) - The time for diffusion is the time required for the substance to moves randomly from a region of high concentration to a region of low concentration.
STEP 1: Convert Input(s) to Base Unit
Standard Deviation: 1.33 --> No Conversion Required
Time for diffusion: 7 Second --> 7 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = ((σ)^2)/(2*t) --> ((1.33)^2)/(2*7)
Evaluating ... ...
D = 0.12635
STEP 3: Convert Result to Output's Unit
0.12635 Square Meter Per Second --> No Conversion Required
FINAL ANSWER
0.12635 Square Meter Per Second <-- Diffusion Coefficient
(Calculation completed in 00.004 seconds)
