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.
Mass Transfer Coefficient formula
| \(\large{ K = \frac {\dot {m}_t }{A \; \Delta F_c} }\) |
Where:
| Units | English | Metric |
| \(\large{ K }\) = 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 | \(\large{\frac{lbm}{sec}}\) | \(\large{\frac{kg}{s}}\) |
