Like in the convection heat transfer process, the convective mass transfer
of species i from the moving bulk uid to the solid surface is given by a con-
vection rate equation analogous to Newton’s law of cooling as

where h

is called the convection mass transfer coefcient or mass lm coef-
cient. The dening equation for the convection mass transfer coefcients is
obtained by comparing Equations 6.59 and 6.81 as
