Convective mass transfer coefficient units. Different types of mass transfer coefficients .

Convective mass transfer coefficient units. The mass transfer coefficient k ' c is a proportionality constant that relates the molar flux (units of moles per unit time per unit area) to the molar concentration driving force. III. It is commonly applied to the calculation of heat transfer in heat exchangers, but can be applied equally well to other problems. Mass transfer coefficients are crucial parameters that describe the rate at which mass moves from one phase to another, typically in a system involving diffusion or convection. However, there are convective fluxes in mass transfer, even on a molecular level. Dimensional analysis in mass transfer Review—compare to heat Engineering quantities of interest Data correlations for (Sh or Nu convection Mass transfer by convection involves the transport of material between a boundary surface (such as solid or liquid surface) and a moving fluid or between two relatively immiscible, moving fluids. Mass transfer coefficient units (mol/s)/ (m 2 ·mol/m 3) = m/s Note, the units will vary based upon which units the driving force is expressed in. This document discusses convective mass transfer and mass transfer coefficients. 3 Diffusion flux Just as momentum and energy (heat) transfers have two mechanisms for transport-molecular and convective, so does mass transfer.
