## Mass Transfer Coefficient based on Film Theory Solution

STEP 0: Pre-Calculation Summary
Formula Used
Convective Mass Transfer Coefficient = Diffusion Coefficient/Film Thickness
kL = DAB/δ
This formula uses 2 Variables
Variables Used
Diffusion Coefficient - The Diffusion Coefficient (DAB) is the amount of a particular substance that diffuses across a unit area in 1 s under the influence of a gradient of one unit. (Measured in Square Meter Per Second)
Film Thickness - The Film Thickness is the thickness between the wall or the phase boundary or the interface to the other end of the film. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Diffusion Coefficient: 0.005 Square Meter Per Second --> 0.005 Square Meter Per Second No Conversion Required
Film Thickness: 1E-05 Meter --> 1E-05 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
kL = DAB/δ --> 0.005/1E-05
Evaluating ... ...
kL = 500
STEP 3: Convert Result to Output's Unit
500 Meter per Second --> No Conversion Required
500 Meter per Second <-- Convective Mass Transfer Coefficient
(Calculation completed in 00.000 seconds)
