Mass Transfer Coefficient

Mass transfer coefficient, abbreviated as K, a dimensionless number, is a porportional constant to the difference in the concentrations and the rate of mass transfer.

\(\large{ K }\) = mass transfer coefficient	\(\large{dimensionless}\)
\(\large{ \Delta F_c }\) = driving force concentration differential	\(\large{lbf}\)	\(\large{N}\)
\(\large{ A }\) = effective mass transfer area	\(\large{ft^2}\)	\(\large{m^2}\)
\(\large{ \dot {m}_t }\) = mass transfer rate	\(\large{\frac{lbm}{sec}}\)	\(\large{\frac{kg}{s}}\)
