# Mass Transfer Coefficient

## Mass Transfer Coefficient formulas

\(\large{ K = \frac {\dot {m}_t }{A \; \Delta F_c} }\) | |

\(\large{ K = \frac { Sh \; D} {l_c} }\) | (Sherwood number) |

### Where:

\(\large{ K }\) = mass transfer coefficient

\(\large{ l_c }\) = characteristic length

\(\large{ D }\) = diffusion coefficient

\(\large{ \Delta F_c }\) = driving force concentration differential

\(\large{ A }\) = effective mass transfer area

\(\large{ \dot {m}_t }\) = mass transfer rate

\(\large{ Sh }\) = Sherwood number
