a. If the liquid film mass-transfer coefficient k = 0.01 gmole/
m². s, and the gas film mass-transfer coefficient ky = 0.02
gmole/m². s, what is the overall mass-transfer coefficient
based on the gas phase driving force, and the % resistance to
mass-transfer in the gas phase?
Transcribed Image Text:b. If the liquid film mass-transfer coefficient is still kx = 0.01
gmole/m². s, what is the new value of ky required to make
the process 10% gas phase mass-transfer controlling?
C.
