What is Fick's law and flux , total flux,molar flux and its related terms in mass transfer ?
Homework Answers
Answer:
Fick's law
it gives relationship of rate of diffusion and surface area, concentration difference and thickness.
Rate of diffusion directly proportional to surface area and concentration gradient. And inversely proportional to thickness.
Where
J = molar flux
D = diffusion constant
C = concentration
x = thickness
Here, Flux is given as the Rate of diffusion per Unit area.
The total flux is the sum of convective flux and diffusion flux.
Convective flux results from convective transport.
Molar flux is defined as a Number of moles transfer per unit area and per unit time.
