A cubic volume which is $1cm$ on each sde is moving to the right in the $+z$ direction with a bulk velocity of $2c\frac{m}{s}.$ In the volume at steady state there are $3$ moles of A $($Mass flow rate $=2\frac{g}{m}ol),2$ moles of $B($Mass flow rate $=3\frac{g}{m}ol)$ and $4$ moles of $C($Mass flow rate $=4\frac{g}{m}ol).$ Molecule A diffuses in $+z$ direction with a diffusion rate of $4mo\frac{l}{s}$ and molecule $B$ diffuses in the opposite direction with a diffusion rate of $2mo\frac{l}{s}.$ Molecule $C$ is under the effect of convective flow only. Calculate:
