Time for Diffusion given Standard Deviation Solution

STEP 0: Pre-Calculation Summary
Formula Used
Diffusion Time = ((Standard Deviation)^2)/(2*Diffusion Coefficient)
tD = ((σ)^2)/(2*D)
This formula uses 3 Variables
Variables Used
Diffusion Time - (Measured in Second) - Diffusion Time is the time required for the substance to moves randomly from a region of high concentration to a region of low concentration.
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.
Diffusion Coefficient - (Measured in Square Meter Per Second) - Diffusion coefficient is the proportionality factor D in Fick's law .
STEP 1: Convert Input(s) to Base Unit
Standard Deviation: 1.33 --> No Conversion Required
Diffusion Coefficient: 800 Square Meter Per Second --> 800 Square Meter Per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tD = ((σ)^2)/(2*D) --> ((1.33)^2)/(2*800)
Evaluating ... ...
tD = 0.0011055625
STEP 3: Convert Result to Output's Unit
0.0011055625 Second --> No Conversion Required
FINAL ANSWER
0.0011055625 0.001106 Second <-- Diffusion Time
(Calculation completed in 00.004 seconds)
