A one-dimensional problem on unsteady diffusion of
a distributed substance through a conventional
diffusion boundary layer is formulated and solved.
Based on its solution relations are obtained for
calculation of the instantaneous and mean mass
transfer coefficients for the times corresponding
to layer formation. A procedure is proposed for
calculation of the mentioned coefficients using the
known dimensionless relations derived for the
steady process.
